T1 Interface - Toshiba Strata DK14 General Description Manual

T1 Interface

The T1 Interface provides 8, 16, or 24 multiplexed, simultaneous two-way voice channels for cost-
effective connection to high quality, digital CO services. This enables the system to connect to a
CO, another DK424 system, or other telephone systems.
Each T1 channel can be individually configured for ANI, DNIS, loop and ground start operation,
DID operation, or Tie line operation. Both Super Frame and Extended Super Frame modes are
supported. T1 Interface requires the installation of a Telco or customer-provided Channel Service
Unit.
T1 DID hookswitch flash capability provides hookswitch flash operation on T1 two-way DID,
ground start, and Tie lines. This improves DID functionality in T1 applications. This feature
requires the RDTU2 T1 card.
For E&M Tie lines, configured incoming 800, or other services, an answering position or DN must
be provided to answer and transfer calls, because all calls are routed to one number. This applies
for AT&T Megacom™ and like services. With multiple DNs, a Megacom call can be answered
from any phone having the corresponding DN.
Ground start operation must be used with ACD or Auto Attendant. T1 loop start lines do not have
any disconnect supervision.
Benefits
Provides economic advantages using the high-traffic capacity of 24 multiplexed, simultaneous
two-way channels. T1 users also benefit from the increased quality of digital transmission. Access
to the T1 interface is completely transparent to the station users.
