Access portions of such circuits are assigned to a special AT&T MCN. Therefore, these circuits will not appear in the customer's circuit inventory. To view and/or create a ticket for such a circuit, customer must be provisioned for the special AT&T MCN. When a ticket is created for such a circuit, the service ID is changed at the AT&T eMaintenance Service Center and forwarded to the appropriate Work Center.
ADSL offers downstream transmission rates from 1.5 Mbps to 8 Mbps, and upstream rates from 16 Kbps to 640 Kbps. The maximum working distance for ADSL from the Central Office is up to 18,000 feet (approximately 3 miles or 4 kilometers).

AT&T VPN service runs over the MPLS
public IP network, which lets users set up a fully meshed IP VPN. The advantage
of MPLS-based VPNs is that service providers still participate in routing for
customers, but the management overhead is significantly less and therefore
cost savings can be passed down to the customer. By default all customer routes
are kept completely isolated, which provides enhanced security. In addition,
an MPLS-based network has built-in mechanisms that can deal with overlapping
customer addresses.
ATM technology can transmit a large quantity of data, voice, and video over
fiber-optic networks simultaneously. Because ATM is designed to be easily implemented
by hardware (rather than software), faster processing speeds are possible.
The Auto-Status Notification window
displays ticket and test events. If there are no test and/or ticket
events to report, a message is displayed that says so.
Whenever there is a change in the event status between notification updates,
the affected items in the Ticket Auto-Status area change color,
as follows:
The DS0 Auto Test tests CPE DSU and CSU, and the AP OSU, if necessary.
The DS1 Auto Test first performs a Quick Monitor Test, then
performs intrusive testing on the section with the problem, if necessary.
The Auto Test is a subset of the Exhaustive Auto Test. For more
information, see the DS0 Auto Test description
or DS1 Auto Test description.
Automatic Speech Recognition allows you to provide automated voice
service to the approximately 17% of U.S. households who use rotary
dialing. In the International marketplace, this
flexibility makes it even easier for you to do business with international
callers. Many international locations either do not use touchtone dialing
or do not have a touchtone frequency that meets U.S. standards for touchtone
dialing. Automatic Speech Recognition makes it possible for your company to
handle these international callers without the need for a live agent,
resulting in significant cost savings for your center.

Circuit-level subnetworks are typically created when two or more companies share an
MCN. Circuit-level subnetworks let a company's personnel work with their own circuits
without being able to see those of the other company(s) provisioned under that same
MCN.
Circuit-level subnetworking is performed at the company level only.
The CAT should be run after running an Auto Test. Since the Auto Test lasts 16
minutes, it makes sense to choose a test duration longer than that. However,
since the CAT test is always an intrusive test that will put the entire T1 circuit down,
you may only want to choose a duration that you're willing to be out of service for.

The access to the Frame switch located in the AT&T central office is usually an ASDS-type circuit. When the data enters the switch, it is transmitted via packet data, the most available route. The customer only pays for service beyond the switch when it is being used.
With Frame Relay Plus, AT&T proactively monitors the customer network for outages and provides network performance information up to the application level, enabling faster trouble isolation in the customer's end-to-end network.
Frame Relay Plus comes with an extensive set of Web-based tools for tracking installation progress, monitoring network status, and viewing network performance information.
Free-format circuits can range from 1 to 25 characters and can contain nearly any printable character.

Crosstalk is a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit. In a telephone circuit, crosstalk can result in your hearing part of a voice conversation from another circuit. The electromagnetic interference that causes crosstalk can occur in microcircuits within computers and audio equipment as well as within network circuits.

IMA allows ATM traffic to be inversely multiplexed across multiple carrier access lines in a cyclic round-robin scheme for putting cells on circuits: the first cell is sent on the first circuit, the second on the second, and so on. Cells are then reassembled in their original order at the receiving end. Unlike bit-based inverse multiplexing, IMA allows circuits to be added and dropped without losing cells.
One of the T1s in an IMA arrangement is designated as the primary T1 circuit. If you try to create a ticket on an IMA circuit that is not the primary T1, a warning pop-up window opens stating that a ticket must be created on the listed primary circuit before one can be created on any other circuit in this bundle.
Nodal services directly connect the client premises with their nearby AT&T Serving Office via private line access/egress.
INCS places a CLNE at the customer's premise to convert the customer's existing technology/equipment (e.g., voice PBX and FRS router) into ATM technology. In addition to ATM technology, compression and IP technology are utilized, letting the customer take advantage of the ATM integrated access technology to dynamically allocate their bandwidth while extending AT&T's network right to their location.
As each call arrives on the network, the network reads the information such as the caller's telephone number, the 800 number dialed, and the caller-entered digits (i.e., credit card numbers) and transmits it to the Customer Routing Point on the customer premises.
The CRP, which stores the customer's unique routing data and arrangements, then tells the network where to route the call.
ICP crosses all stratas and provides customers with the capability for directly controlling the routing of their inbound Toll Free traffic. ICP provides per-call routing of Inbound traffic by enabling customer-owned CRPs to interact with AT&T owned and operated Network Control Points (NCPs).
This ICP feature capability provides superior real-time control over distributing and completing incoming calls to the appropriate resources available at various customer locations. It also allows discrete differentiation of callers, thereby letting them be assigned the appropriate priority for call treatment.
The following services can subscribe to ICP:
Conducting an intrusive test on one channel of a T1.5 multichannel pipe may affect other channels on that pipe, taking them out of service during testing. When testing is complete, the T1.5 is brought back into service.
Intrusive test types include Auto Test, Exhaustive Auto Test, and Quick Test.
For DS0 private lines, intrusive tests are automatically run because they are the only type of testing available. For other types of DS0 circuits and for DS1 circuits, non-intrusive tests are performed first. These are the Quick Monitor Test for DS0 circuits and the Enhanced Monitor Test for DS1 circuits. Only if these preliminary non-intrusive tests indicate that there is a problem will intrusive testing be performed. Since the circuit being ticketed is already in trouble, taking the circuit out of service should not be an added inconvenience but should speed up ticket resolution.
IRUs are specified in terms of a certain number of channels of a given bandwidth and are granted by the company or consortium of companies that built the (usually optical fiber) cable.
This digital DS1 level service provides direct access between a customer PBX to the 4E for the integration of switched nodal services over 23 "B" channels per facility. The "D" channel (24th channel) provides out-of-band signaling.
Using a one-step dialing process, AT&T Business customer's clients simply dial the customer's international Toll Free number, and the call is connected to a designated customer location in the U.S. Clients don't need operator assistance to make the call. The Toll Free number is unique to each country because ITFS numbers are in a national numbering format. This numbering format is similar to an "800" number in the U.S., and is easily recognized as Toll Free by callers in other countries.

Jitter amplitude is measured in Unit Intervals (UI); each unit interval is equal to one bit time. This is a measure of how far the bits are sliding, usually measured peak to peak.
The shifting of the bit arrival time is not random. Frequency components are measured in Hertz. Lower frequency jitter is easier to follow than higher frequency jitter.
Jitter is the name of an AT&T VPN trouble type. The corresponding trouble code for this trouble type is 468.

Local Private Line service provides a dedicated circuit between two locations, for example:
Local Private Line service is often used for tie-lines, IXC access, WAN circuits, and dedicated Internet access.
Local Private Line service is provisioned with T1 or T45 (T3) facilities; connectivity is usually provided through cross-connect devices and/or multiplexers rather than through switch terminations.
On an optical signal, LOF could point to defective local or immediately upstream circuit packs, a regenerator, or any cables, connectors, or optical line systems in between.
On an electrical signal, LOF could also be experiencing propagating OOFs from any upstream technology in the path.
Sending a loopback test to each telephone system piece of equipment in succession, one at a time, is a technique for isolating a problem. (The loopback can be compared to the Internet's ping utility, which lets you send a message out to a host computer on the Internet. The ping echo tells you whether or not the host computer is available and the time the signal took to return.)
Used in ASDS maintenance.
An LOS alarm typically occurs when there is a break in a circuit. The network equipment at the AT&T Serving Office detects the break and forwards an LOS to the alarm-monitoring equipment.
LOS occurs when no pulses are received for 150 millisec. The IU inserts an AIS (all ones) downstream and activates a local alarm.

Multipoint circuits are designed to minimize total network cost subject to either a maximum number of drops or a maximum average response time on each circuit.
Multipoint circuits provide customers with the capability to transmit information between three or more stations with a bridging function. This functionality operates through the normal telephone switched network and provides continuing service in the event that the regular circuit should fail.
For example, in a typical Private Line multipoint circuit configuration, the path or "circuit" is assigned a circuit ID (e.g., AREC111111111ATI), and each circuit location is assigned a circuit location number (e.g., CKLID 0001, CKLID 0002, CKLID 0003).
A multipoint configuration may also have a circuit location number designated as a master station or as a secondary station. If no such designation is made, the CKLID with the lowest number (i.e., CKLID 0001) is the default location.
Features include Call Detail Report, a monthly Executive Summary Report, flexible billing, electronic funds, and courtesy phones. Applications include polling, opinion surveys, and consumer information.
MultiQuest 900 differs from 800 Service in that the caller is charged for the call when using MultiQuest 900.

AT&T NAAR allows you to reroute calls to alternate locations if the primary location is busy. You specify what you consider a "busy" location by defining the maximum number of calls that works best for your business. When the number of calls in progress meets the maximum condition you previously set, subsequent calls are instantly rerouted to the next available termination point. NAAR allows a customer to reroute calls up to 99 alternate locations.
While the feature Next Available Agent Routing (NAAR) redirects calls, another feature of this service, Network Queuing, provides automatic queuing on the AT&T Network . . . without any additional investment in equipment.
For example, when NAAR is rerouting customers to available terminations or when all agents and locations are busy, Network Queuing will automatically queue calls in the network. While in queue, your customers will hear an announcement saying their call is being queued. Then the caller will hear music. The caller is reassured, "Your call is important to us, please hold on.quot; This message will play intermittently until the next agent becomes available. Your customers won't hear a busy signal and you won't lose their valuable calls.
Also known as Alternate Terminating Sequence.
"No Access" occurs when the customer has denied AT&T access to the circuit. The customer is billed during No Access.
Also known as "Delayed Maintenance".
For example, when a facility is open only from 8am to 5pm and a ticket with Dispatch Authorized is created after hours, that dispatch must be scheduled for the next day; the amount of time AT&T had to wait before dispatch is the no access time value.
A nodal service refers to a dedicated access (DS0 and DS1) service originating at a customer location and terminating on a 4E, 5E, or DMS switch. A customer identifies a nodal service trouble with either a telephone number or a circuit ID.
In order to be considered nodal, one end of the call is switched by the LEC prior to entering or exiting the LD carrier's environment; access is analogous to a private (digital) line from the customer's premises to the LD carrier's switch.
Examples of nodal services include Megacom 800 and Software-Defined Network (SDN).
Noise is considered to be any random disturbance or unwanted signal in a communications system which tends to obscure its clarity or interfere with its transmission.

Ping can also be used with a host that is operating to see how long it takes to get a response back, and can be used to get the numeric form of the IP address from the symbolic domain name.
The acronym "PING" (Packet Internetwork Groper) was created to onomatopoetically emulate the submarine term for the sound of a returned sonar pulse.
When you create a ticket on an IPFR circuit in AT&T eMaintenance, the Create Ticket for Circuit Screen asks if you can ping the Provider Edge Router and, if "Yes," if you can then ping the Customer Edge Router.

Circuits can be limited to one protocol or several. For example, PVCs can be set to have either Translation Mode to use multiple protocols or Transparent Mode, where both endpoints must use the same protocol.
The Pacific time zone includes the following US states:
...and Canadian provinces:
A PVC lets a Frame Relay connection act as the equivalent of a "virtual" circuit switched leased line.
Frame Relay Service has two basic offerings: connections from customer location to the Frame Relay Network provided by dedicated private lines, and connections across the Frame Relay Network provided by PVCs. A connection from a customer location to the Frame Relay Network is commonly referred to as a "port" because the circuit terminates on a port of a Frame Relay switch. A PVC connects two Frame Relay ports.
The PVC Monitor Test monitors the Frame Relay PVC to validate clear transmit/receive of packets, and validates that the PVC is clear across the AT&T network.
Note: PVC Monitor Test cannot be performed on some circuits.

Route It! allows you to design new routing plans or download and change existing plans off-line, and then upload those plans to the AT&T Network.
A router is located at any juncture of networks or gateway, including each Internet point-of-presence. A router is often included as part of a network switch.
A router creates or maintains a table of the available routes and their conditions and uses this information along with distance and cost algorithms to determine the best route for a given packet. Typically, a packet may travel through a number of network points with routers before arriving at its destination.

By creating such a scheduled maintenance window, a user is instructing AT&T systems and people to suspend Proactive Maintenance on a circuit, since the planned maintenance may cause alarms that are not true troubles that require ticket creation, tracking, etc.
In typical mainframe networks, the host mainframe is the primary or master station, and workstations and other devices are secondary stations. Each secondary station has its own address. Typically, multiple devices or secondary stations are attached to a common line in what is known as a multipoint or multidrop arrangement.

The primary function of the Service Assurance offering is to provide temporary service arrangements to customers experiencing some form of service-affecting trouble. However, Service Assurance is often applied when a customer wishes to reroute its traffic during "Planned Maintenance" events (such as CPE testing, etc.) in which there are no service-affecting troubles.
In AT&T eMaintenance, Service Assurance is requested during the ticket creation process, where the Service Assurance Request questionnaire is filled with the appropriate rerouting information.
Possible values include:
Valid characters for service ID alias include: letters, numbers, spaces, commas (,), ampersands (&), apostrophes ('), dashes (-), underscores(_), and dots (.); and the percent sign (%) as the wildcard character.
Examples include:
SINA1 is DS1 access with M24 and at least one channel of voice service. Other services on the DS1 may include Private Line, Frame Relay, or MIS (IP).
SINA2 is DS1 access with inbound and outbound voice service and no M24.
SINA3 is DS1 access---the same as SINA1, but with ISDN.
SDDN uses the 4ESS switch with a wideband time slot interchange and requires dedicated access. SDDN has high performance and reliability. SDDN uses network-based features. Applications include data overflow, high-speed mainframe connectivity, and video teleconferencing.
SDN provides network-based features and management capabilities that are typically found in private networks, such as flexible routing functions, a multiple dialing plan, call screening, authorization codes, remote access, security codes, and plus volume discounts.
SDN can be used in a hybrid architecture in conjunction with the customer's private network. An SDN customer may add or delete locations on the network easily without redesigning the network.

Masquerading users can take on the privileges of the subdivision(s) they work with. Subdivisions can contain GRCs, SOCs, and other customer information.
NOTE: Subnetworking is not available to POS circuits.
With an SVC, the user defines the end-points when the call is initiated that are subsequently terminated at the end of the call. With a PVC, the end-points are predefined by the network manager. A single virtual path may support multiple SVCs.
Switch Diversity options provide robust network solutions and the flexibility to select feature options dependent on your specific diversity requirements. Switch Diversity options also serve to protect your service in the event of a failure at a switch or POP.
AT&T eMaintenance supports creating a ticket on switched services when the phone number has an MCN.

The dialing format for UIFN is:
...where the plus sign ("+") represents the International Access Code (the code that a customer would dial to initiate an international direct dialed call) followed by "800" and then 8 digits. A customer's UIFN will be identical in every country offering service. The only part of the number that will vary from country to country will be the International Access Code dialed.
UIFN includes all customers currently subscribing to International Toll Free Services (International Toll Free and International Toll Free via AT&T Direct) and customers desiring a single International Toll Free Number worldwide.

The VLAN controller can change or add workstations and manage load-balancing and bandwidth allocation more easily than with a physical picture of the LAN. Network management software keeps track of relating the virtual picture of the local area network with the actual physical picture.
VLANs are likely to be used with campus environment networks.
In contrast to a system of owned or leased lines that can only be used by one company, a VPN gives a company the same capabilities at much lower cost by using the shared public infrastructure rather than a private one.
In contrast to a system of owned or leased lines that can only be used by one company, a VPN gives a company the same capabilities at much lower cost by using the shared public infrastructure rather than a private one.
In traditional IPV4 backbone networks, if ten different customers were attached to a PE, all ten customers would use the same global routing and forwarding table (a single table for everyone).
With MPLS, each of the ten VPNs would have a VRF dedicated to that VPN. Instead of one large global routing table, there are many small VRF tables. This keeps security tight between different customer VPNs.
VTNS operates like a private system---it is designed to meet unique needs and to be responsive to the needs of customers with complex telecommunications requirements.
VTNS allows businesses to use portions of the AT&T switched network in a partnership with their dedicated private line networks to create a virtual private network within the AT&T Worldwide Intelligent Network.
