Description
D-channel card type.
Serial Data Interface (SDI) Card number
Number the SDI cards logically with the system.
MSDL application small system Card number
DCHI small system Card number
Must be set to 1.
D-channel for ISDN PRI only.
Interface type.
PRI2 card number. (Must match entry for CDNO).
Net: network, the controlling switch.
User: slave to controller.
Software release of far-end. This is the current software
release of the far-end. If the far-end has an incompatible
release of software, it prevents the sending of application
messages. For example, for Network Ring Again.
D-channel clock type for signaling.
Source of D-channel clock is external to DCHI card (in this
case the DTI/PRI circuit card). Normally, EXT is used for PRI/
ISL.
Note: Do not confuse this clock with the E1 span Clock
Controller found on the NTAK10/79. This clock is in reference
to the DCHI synchronous mode of operation.
Note: If directly connecting two DCHI ports with out the use
of modems, set "CLOK" to "EXT" on one side and "INT" on the
other.
