CallPilot T1 interface hardware
ATTENTION
Line Side T1 cards (SL-100 only)
The Line Side T1 card provides T1 connectivity for SL-100 CallPilot
installations. The card multiplexes 24 channels into a T1 signal. The card
installs in the Intelligent Peripheral Equipment (IPE) shelf of an SL100 and
appears to the switch as 24 analog line cards. The Line Side T1 Interface
(LT1) card (NT5D11) is installed in the IPE module (NT8D37).
LT1 parameters must match those of the T1 Intel board. For proper
operation of the system, ensure that the switch settings match.
Note: The SL-100 switch can use Line Side T1 cards or an external channel
bank for call lines. The DMS-100 switch does not use Line Side T1 cards
and requires an external channel bank for call lines.
If using line cards, you must have a sufficient number of Line Side T1 cards
for the number of channels purchased. Refer to Line Side T-1 Interface
(LT1) for IPE Services Guide (555-4001-022) for instructions on installing
Line Side T1 cards
Channel banks (DMS-100, or SL-100 not using Line Side T1
cards)
Channel Banks multiplex incoming signals into a higher rate output digital
signal. For CallPilot, the Channel Banks convert 24 analog lines to 1 T1
link.
T1/SMDI and CallPilot Server Configuration
A 4 to 9 second silent delay is experienced when using any
of the transfer, thru-dial, or call sender functions before
ring back is heard. The debounce value may need to be set
to 25 or higher. If the default value of 13 is configured, call
transfer, thru-dial, and call sender functions may not
function in some implementations. This applies to CallPilot
T1 integrations such as SL100/CS2100 and DMS/CS2000.
