are:
The RLCM-EDC is subordinate to the DMS-100 switch CC and is not
involved in any signaling between the host office and other systems.

Functional limitations

For feature package NTX146AB to work properly, certain conditions must
be observed. These limitations or restrictions may be hardware or
software-dependent, as follows.
Hardware restrictions
The following hardware limitations apply to the NTX146AB software
package:
Software restrictions
Feature package NTX146AB requires the following software packages in
order to operate:
297-8381-550 Standard 02.02 April 1999
dial tone
audible ringing
warble (MDC Meridian business set ringing)
busy tone
reorder tone
receiver off-hook (ROH) tone
A maximum of 640 lines can be served by one RLCM-EDC, however
the RLCM-EDC is engineered for a non-blocking configuration for up to
140 EBS lines, in the initial application.
A minimum of two and a maximum of six DS-1 (T-span) links connect
the RLCM-EDC with the host office.
All DS-1 links to the RLCM-EDC must terminate on the same host
LTC+. The two message supporting links must terminate on different
NT6X50AB cards.
The maximum power input to the RLCM-EDC bay is 35A at –48V.
