TBOS Telemetry Cable Installation -
Front Access
Description
NOTE
:
TBOS is not available in Release 13 software.
NOTE
:
TBOS telemetry cable installation should be performed if specified in the
order.
TBOS is a serial telemetry interface, providing system alarm and status data to a
maintenance center and remote switch (RS) capability from a maintenance center.
One connection from the telemetry equipment provides up to eight displays and
can accommodate up to eight DDM-2000 OC-3 shelves (each shelf is assigned a
display). A central office shelf and its associated remote terminal shelf (or shelves)
will typically be assigned displays associated with this single interface connection.
Additionally, other DDM-2000 OC-3 shelves in the bay may be assigned remaining
displays associated with the single interface connection. This is accomplished
using intershelf mult cabling. Bays equipped with more than two DDM-2000 OC-3
shelves may require additional TBOS connections to the telemetry equipment.
Connection of TBOS telemetry requires a TBOS telemetry system in the office,
and thus TBOS telemetry is only used in a central office environment.
There are two options for cabling TBOS:
■
Cable directly to TBOS equipment
■
Cable to another shelf.
As mentioned above, at least two TBOS cables are required to be routed from the
TBOS telemetry system to the DDM-2000 OC-3 bay to accommodate the
maximum of six shelves in a bay.
The cable for multing TBOS also provides the intershelf mults for the craft
interface terminal (CIT) and modem. This mult cable will be installed per
"Intershelf Mult Cable Installation - Front Access".
