Description
NOTE
:
TBOS is not available in Release 13 software.
Telemetry byte-oriented serial (TBOS) is a serial telemetry interface providing
system alarm and status data to a maintenance center and remote equipment
switch capability from a maintenance center.
A cable connection from the telemetry equipment provides up to eight displays
and can accommodate up to eight DDM-2000 OC-3 shelves (one display/shelf). A
central office shelf and its associated remote 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 by 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 processor in the office,
thus TBOS telemetry is typically (only) used in a central office environment.
NOTE
:
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 accommo-
date the maximum of six shelves in a bay.
NOTE
:
The TBOS intershelf mult cable also provides the intershelf mult for the
craft interface terminal (CIT) and modem (if necessary). Information for
installation of the mult cable is provided in the "Intershelf Mult Cable Instal-
lation".
NOTE
:
TBOS telemetry cable options are listed in Table 2-4.
NOTE
:
TBOS telemetry connections are listed in Table 2-10.
