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:
â–
Cable directly to TBOS equipment
â–
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".
