ORDERING INFORMATION
GENERAL DESCRIPTION
T
he Service Node Digital Service Multiplexor (DSM) Shelf
described in this manual is offered in a number of different
configurations. Refer to
Ordering Information
above.
The DSM is composed of two basic modules. Refer to Figs. 1, 2,
and 3 for front, rear, and side views of the 05721 system. The B11-
46112-00 Controller Module and the B11-46113-00 Data Port
Module. The Controller Module is used to interface the 64Kb
channel using a RS-422 interface and to interface the Data Port
Modules. Each Controller can accommodate up to 8 Data Port
Modules. Each Multi Port Module can provide for up to four
RS-232 or RS-422 ports. In this application only the RS-232 ports
will be wired to DB-25 connectors. The total number of ports that
can be provided from a Controller and Port Modules is 32. The
DSM can be optioned so that the channels can terminate at a
location or they can be repeated to the next locations. At the
Service Node, all channels are set for terminal application.
The purpose of this system is to provide RS-232 ports from the
Service Node to every Local Serving Office (LSO) site. This will
allow for transmission of ASCII information on the 64Kb OW
channel of fiber systems such as FT 2000 terminals. This could be
ASCII data such as TL1 messages from Telecom Solutions DCD-23
BITS clock or TL1 messages from other Network Elements (NEs).
This application will also provide for an additional RS-232, 1200
baud port at every LSO. This system will provide for a self healing
ring on the 64 kb channel and it will provide for alarm information
for maintenance and fault location of the ring.
