Emergency Stand Alone - Nortel SL-100 Product Manual

20 C-Side DS1 Links on RCC2/MCRM-S
This feature provides support for a RCC2-to-host LTC/LGC interface with 20
DS1 C-side links. Increasing the number of supported RCC2 C-side links
from 16 links to 20 increases the number of speech channels from 382 to
478. This development accommodates increased traffic needs, expanding
the C-side traffic capacity by 25%.
The RCC2 shelf requires hardware to support the expansion to RCC2
C-side links. These hardware items are listed below:
•
•
•
The RCC2 shelves with the expanded C-side configuration (holding 20 links)
can co-exist with 16 C-side link RCC2 shelf configurations in the same office.
The hardware is supported in software version XPM05 and up.
The RCC2 shelves with the expanded C-side configuration (holding 20 links)
can co-exist with 16 C-side link RCC2 shelf configurations in the same office.
When provisioning for 20 C-side DS1s from RCC2 to host, note that the host
must have a dedicated controller for the 20 RCC2 ports.
Upgrading to MSL11 with RCC2s also require a hardware change from
NTMX77 to NTAX74 when going to the MSL11 load, prior to the PM Software
Upgrade. The NTMX77 is no longer available in MSL11 for the RCC2.

Emergency Stand Alone

Emergency Stand Alone (ESA) provides the RSC remote peripherals with
the intelligence to allow continued service for intraswitched calls, when
communication to the Meridian SL-100 host is lost. This includes support of
basic station-to-station calls within the remote. Because they require the
use of a modem in the host, Attendant Consoles are not supported during
ESA operation.
When communication is lost on the primary DS1 links to the Meridian
SL-100 host office, the remote automatically enters the ESA mode. ESA
operation continues until communication is restored over at least one of
the primary DS1 links. During entry to the ESA mode, established calls
are not dropped.

NTMX81 packlets.
The NTMX81 packlets, which are smaller than the existing packlets.
A matrix pack card (NTMX75DA), which supports the configuration, is
required. This NTMX75DA matrix card maps the DS1 links (both new
and existing) to the DS-30 links.
