MCDS backplane
The MCDS backplane, which is part of the shelf assembly, is provided with
two-sided circuitry. It is equipped with nine 160-pin connectors to receive the
interface and power supply circuit packs. It is also equipped with two
25-pair standard telecom-type plugs to connect to the SL-1 switch and
32 female-type, standard 25-pin, RS-232-C connectors to provide interface to
the computer ports. The backplane is also provided with an insulator sheet on
the rear surface to prevent accidental shorting of the traces with metal
connector hoods.
MCDS-AC
The MCDS-AC provides the drivers and receivers to meet the EIA standard
RS-232-C electrical interface specifications.
Traffic measurements provided for data traffic and feature usage for data calls
are the same as for voice traffic from telephones. Refer to Traffic
Measurement: Formats and Output (553-2001-450) for further information
on available traffic measurement.
Implementation of the SL-1 data feature requires additional memory for each
ADM added. Requirements for unprotected and protected data store and real
time are given in Meridian Data Features: Traffic Engineering and
Configuration (553-2731-151).
A manual remote loopback testing capability is provided for isolating ADM
and ASIM faults. Information on remote loopback testing procedures is given
in Meridian Data Features: Operations and Tests (553-2731-300).
All resident maintenance programs, maintenance overlays, and diagnostics
which apply to telephones and line cards are also applicable to the ADM,
AIM, ASIM, and AC ports, DLC, AILC, and MPLC.
