Configuring The Physical (T1) Link Interface; Link Redundancy - Paradyne COMSPHERE 6800 Series Multiplexer Management And Configuration Manual

Management System Multiplexer Command Reference Manual.

Configuring the Physical (T1) Link Interface

In the multiplexer network, T1 facilities interface at the 740 multiplexer via aggregate link
interface modules, and at the 745 via the T1 line interface modules; 56K/64K digital facilities
interface at the 74x-56K multiplexer via aggregate link interface modules. All the parameters of a
link, including clocking, redundancy, line encoding, physical attributes, and alarm options, can be
configured, along with the state of the links and the 745's DS1 modules. Features configured on
physical links are described below.
Physical Links on an ACCULINK node can be configured as connected to Series 700 nodes or to
other objects. The links are configured as connected to other when they are connected to
non-Series 700 nodes, such as DACS nodes, PBXs, etc.
You can configure both links on a Series 700 to Series 700 facility or you can configure a single
link at a time. The NMS can verify that the configuration of the links on each end of the T1 facility
are compatible.
The facility name, as found in the facility profile tables, can be used to specify the links to be
configured. If the facility name is entered, the node and link information will be determined from
the facility profile data; if a profile is found, the node and link information cannot be changed. If
the node and link information is entered instead of the facility name, the facility name will be
determined.

Link Redundancy

Nodes can be equipped with one or two (for optional redundancy) modules per link. If a link is
configured for redundancy (not applicable to the 741 and 742 chassis), it is configured as one of
the following.
single
dual
none
6800-A2-GB21-10
Two modules are connected to a single facility via a Y cable. For 740 chassis nodes,
single is also used to indicate no link redundancy in this case, the redundant link
information should be left blank. (This is the only option for 741 and 742 chassis nodes.)
Two modules are connected to two separate facilities.
Only valid for the 745; one module is connected to a single facility.
