Analog Key Line (Ground Start)
When a circuit is "seized", the central office sends "notice" to the customer premise equipment (CPE), and the CPE must respond to the "notice" before dial tone is provided. Ground Start prevents "glare".
Analog Key Line (Loop Start)
Loop Start signaling technology does not respond to a notice from the Central Office indicating that a circuit has been seized. This situation can cause "glare" - meaning both the customer premise equipment (CPE) and the Central Office "seize" the circuit at the same time. When "glare" occurs, the customer attempts to make a call, does not hear a dial tone, receives an incoming call, and neither party heard a ring tone.
Analog PBX Trunks (DID)
An Analog PBX (DID) Trunk allows incoming calls to be terminated directly to an extension behind customer premise equipment (Key System, Channel bank, PBX) without the need for an attendant to complete the call. the service is one-way only.

ATM
Asynchronous Transfer Mode is a standard for cell relay. It is a dedicated-connection switching technology that organizes digital data into 53-byte cells or packets and transmits them over a medium using digital signal technology. Individually, a cell is processed asynchronously relative to other related cells and is queued before being multiplexed over the line. Because ATM is designed to be easily implemented by hardware (rather than software), faster processing speeds are possible. The pre-specified bit rates are either 155.520 Mbps or 622.080 Mbps. Along with SONET and several other technologies, ATM is a key component of BISDN. ATM can carry voice, data, and video.

Identifies the 4E Switch memory options for routing calls. The AT&T switch remembers which channel received the last call and routes subsequent calls to the next sequential channel in the hunting arrangement.
AT&T Voice DNA (Dynamic Network Application)
(aka IP Centrex) A virtual hosted IP PBX service that provides carrier-class primary local service and features (eg; N11, 8YY, PSTN off-net, etc), as well as line side features (e.g call hold, Call waiting, Conferencing)on MIS /AVTS/PNT with VoIP. An end user may manipulate their settings, through the use of a web portal accessible from anywhere through the Internet. End-user can return voicemail messages via email, listen to voice mail messages into email, and review call logs via the web portal. Also technical administrators will have the ability to perform MACDs (Move/Adds/Change/Disconnects) through a separate web portal. The admin portal will also allow administrators to pull usage reports and control feature settings such as limiting the type and/or group of personnel with access 800/900 number dialing. An IP Phone on the users desktop will provide additional functionality too. These phones will retain feature settings and preferences when disconnected and plugged in at a remote location. IP Centrex service resides on the Sylentro Application server, which currently has the engineering capability of 117 total ON Net Centrex features. Not all features will be operational for initial service. Features can be ordered in three &wuot;packages&wuot;: Basic, Basic + and Enhanced. Each feature adds features to the one preceding it. In addition to the three feature packages, a customer can order "a la carte" features, which can be added to the basic plus and enhance feature packages. 11 "a la carte&wuot; features are planned but only three will be available for initial service.

Dial tone is provided by AT&T Central Office. This signaling assumes "non-senderized" (the customer's switch passes or outpulses the digits as they are received) and that the incoming digits will be in dial pulse format only. Upon receipt of an incoming seizure the AT&T switch will not return a wink or any form of signal to indicate readiness to receive digits. It will prepare to collect the dial pulse digits and then will allow 15 seconds for the 1st digit to arrive.
Dial Pulse Wink (DPWINK)
The AT&T switch seizes a trunk towards the customer's switch for an incoming call. The customer's switch detects the seizure and winks back at the AT&T switch. The AT&T switch will delay 70 milliseconds before outpulsing the DNIS in Dial Pulse format.

DNIS allows the customer's terminating equipment to view the original number dialed by the caller, or any number the customer wishes to associate with the original number dialed.

Geographic Restrictions
This feature allows you to restrict outward calling area based on NPA, NPA/NXX, Country or NXX. Calls to these selected locations will then be blocked by AT&T.
Glare
The situation encountered when the same trunk is seized by both an incoming and outgoing call simultaneously. One switch in this case must release the trunk (the PBX is designated as the controlling switch) and the 4ESS will back down allowing the outgoing call to complete. If this situation occurs frequently, the customer may need to re-engineer or add facilities in order to reduce the amount of call blockage. For example, SASS (Shared Access for Switched Services) is a service which permits the sharing of facilities of both inbound and outbound services. To reduce the incidence of glare, the 4ESS and the PBX are engineered to hunt from opposite ends of the Trunk Sub Group (TSG) .

Return to Top
H
Hairpinning
The terms On-net Prefix and Off-net Prefix are sometimes used in the context of Hairpinning. Hairpinning allows Failed Calls to be routed from the PBX back to the AT&T Managed Router. If the Managed router cannot complete the call, hairpinning allows the router to send the call back to the customer PBX with an optional prefix so the call can be completed using another trunk on the PBX. The call will be routed out to the PSTN (or private network) for completion. Hairpinning is an option the customer can select by indicating a PSTN Access Code (Off-net), or a Private Access Code (On-net), which is actually the customer's private network. Also note that hairpinning is specific only to Managed Routers with VoIP Module Cards and is not applicable to IP PBXs.

Hunting
Hunting is the act of searching for an available channel in order to route in incoming call.

This feature allows incoming calls to seek out an available line in a predetermined sequence, called a hunt group. The first line of the hunt group is a billing telephone number that the outside caller dials. If this line is busy, the call is automatically routed to the next Working Telephone Number in the hunt group until an idle line is found. If no lines are available and the customer has voice mail, then the incoming call will be sent to voice mail. If the customer does not have voice mail, the caller gets a busy signal.

SIGI
Signaling from the AT&T switch to the customer's equipment. Options include Touch Tone Wink (DTMF), Multi Frequency Wink, Dial Pulse Wink, Dial Pulse Delay Dial, Seizure Immediate, and Seizure Wink.
SIGI Type: Dial Pulse Delay Dial
This signaling is almost identical to Dial Pulse Wink. The only difference is time allowed for the off hook signal.
SIGI Type: Dial Pulse Wink
The AT&T switch seizes a trunk towards the customer's switch for an incoming call. The customer's switch detects the seizure and winks bcbackt the AT&T switch. The AT&T switch delays 70 milliseconds before outpulsing the Dialed Number Identification Service (DNIS) in Dial Pulse Format.
SIGI Type: Multi Frequency Wink
This signaling is sometimes used with Centrex. The AT&T switch seizes a trunk towards the customer's switch for an incoming call. The customer's switch detects the seizure and winks back at the AT&T switch. The AT&T switch delays 20, 80, or 220 milliseconds before outpulsing the Dialed Number Identification Service (DNIS) in Multi Frequency Format. The outpulsing will be at a rate of either 7 or 10 digits per second.
SIGI Type: Seizure Immediate
The AT&T switch seizes a trunk towards the customer's switch for an incoming call. The customer's switch detects the seizure and provides alerting (ringing). No DNIS digits are outpulsed to the customer switch.
SIGI Type: Seizure Wink
The AT&T switch seizes a trunk towards the customer's switch for an incoming call. The AT&T switch waits 5 seconds for a wink. After receiving the wink, the AT&T switch sends the call. No DNIS digits are outpulsed. This type of signaling is uncommon.
SIGI Type: Touch-Tone Wink (DTMF)
The AT&T switch seizes a trunk towards the customer's switch for an incoming call. The customer's switch detects the seizure and goes off hook (wink). The AT&T switch detects the wink and after a 70, 140, 210, or 280 milliseconds delay, the switch outpulses the DNIS digits.
Signaling
The process by which one location alerts another location on the same channel or network to notify the PBX of a call. If the equipment does not receive the expected signal the call will not be able to terminate. Your customer premise equipment vendor can often provide this information. Types of signaling are Dial Tone, Immediate, or Wink.
Signaling Format
Specifies the physical signaling protocol the T1.5 channels send from the customer premise. Robbed Bit is the signaling format for Non-ISDN service and Q931 (also known as Clear Channel) is for ISDN. Signaling is the process that one location alerts another location on the same channel or network and is used to notify the equipment of an incoming or outgoing call. If the equipment doesn't receive the expected signal, the call won't be able to terminate or originate.
SIGO
Signaling from the customer's equipment to the AT&T switch. Options include Touch Tone Wink (DTMF), Multi Frequency Wink, Dial Pulse Immediate, Dial Pulse Delay Dial, and Dial Tone Start.
SIGO Type: Dial Pulse Immediate
Dial tone is provided by AT&T Central Office. This signaling assumes "non-senderized" (the customer's switch passes or outpulses the digits as they are received) and that the incoming digits will be in dial pulse format only. Upon receipt of an incoming seizure the AT&T switch won't return a wink or any form of signal to indicate readiness to receive digits. It will prepare to collect the dial pulse digits and then will allow 15 seconds for the 1st digit to arrive.
SIGO Type: Dial Tone Start
This signaling is used in most channel bank configurations and assumes the customer's switch is non-senderized. The customer's switch seizes a trunk for the Outbound call. The Channel Bank converts Loop Start/Ground Start to E&M supervision toward AT&T. The AT&T switch detects the seizure and returns dial tone to the PBX to indicate it is ready to receive digits. Digits are outpulsed from the customer's switch to AT&T.
SIGO Type: Multi Frequency Wink
This signaling assumes that the customer's equipment is "senderized." This means that all of the digits dialed are stored in the customer's switch and forwarded to AT&T at the same time. The customer's switch seizes a trunk for an Outbound call. The AT&T switch detects the seizure, hunts for an idle Multi Frequency receiver and after connecting it to the incoming trunk will send a 250 milliseconds wink toward the customer. The customer's switch detects the wink and outpulses the digits in Multi Frequency format.
SIGO Type: Touch-Tone Wink (DTMF)
This signaling assumes that the customer's equipment is "senderized." This means that all of the digits dialed are stored in the customer's switch and forwarded to AT&T at the same time. The customer's switch seizes a trunk for an Outbound call. The AT&T switch detects the seizure and goes off hook toward the customer's switch for 250 milliseconds (wink). The customer's switch detects the wink and outpulses the digits.
