Feature Description
50003510 Revision A 197
Trunk Support - Direct Inward Dial (DID)
The DID trunk types supported are Wink Start, Delay Dial and Immediate Dial. DID Trunks
support Tie, CO, DID, and DISA operation.
Trunk Support - E&M
E&M trunks are supported with the E&M Trunk module on the Universal Card in digital peripheral
bays. The signaling schemes supported include: Type I and Type V, 2-wire or 4-wire. E&M
trunks support Tie, CO, DID, and DISA operation.
Trunk Support - T1
T1 trunks are supported using T1/D4 Channel Associated Signaling (CAS), also referred to as
DS1. T1 Trunk cards support DID, Tie, CO, and DISA operation on a per circuit basis. For each
circuit, the circuit descriptor can be programmed through CDE to alter the signaling scheme to
one of: E&M, DID/Loop-Tie, CO (loop and ground start), DISA E&M, DISA DID/Loop-Tie, DISA
CO (loop or ground start).
The system provides a Stratum 3 or 4 clock source as an integral part of the Main Control Card.
The system can be used in master mode to serve as a clock source for the network, or in slave
mode to use the network as its clock source. In slave mode the system prevents data losses
due to clock rate differences by adjusting its internal T1 clock module to remain in phase with
the incoming frame clock rate.
Uniform Call Distribution (UCD)
Uniform Call Distribution (UCD) concentrates incoming trunk traffic onto one or more special
agent hunt groups. Trained operators (Agents) answer the calls. If all Agents are busy, the
caller camps on and may be connected to a recording hunt group, where the caller hears
recorded announcements. The caller retains his position in the queue. If the Agents are still
busy when the recording ends, the system connects the call to Music-on-Hold (if provided).
After a pre-determined time, the unanswered call is rerouted to a designated answering point.
Vacant Number Intercept
Calls to unassigned (vacant) access codes can be routed to a given answering point for
completion. This point can be an LDN position on the Attendant Console or any valid routing
point. Vacant number intercept points can be programmed to be different or the same for DAY,
NIGHT1, and NIGHT2 modes of system operation.
Voice Mail Support
The SX-200 EL and SX-200 ML systems support the following Voice Mail functionality:
• Centralized Voice Mail
• Voice Mail on COV Ports
• Voice Mail on DNIC Ports
• Voice Mail on ONS Ports
