ONITORING AND OOPBACK
UltraWAN CSU/DSU connectors support central-office switch-initiated
loopback activation and deactivation requests.
Remote Line Loopback activation is supported on T1SF lines via the
in-band, framed, 10 second duration pattern of 00001. Remote Line
Loopback deactivation is supported via the in-band, framed, 10 second
duration pattern of 001.
Remote Line Loopback activation is supported on T1ESF lines via the line
loopback activate request Bit-oriented Protocol (BOP) 0x0EFF pattern
being sent over the Facilities Data Link (FDL) channel. Remote Line
Loopback deactivation is supported via the payload loopback deactivate
request BOP 0x38FF being sent over the FDL.
Remote Payload Loopback activation is supported on T1ESF lines via the
payload loopback activate request Bit-oriented Protocol (BOP) 0x14FF
pattern being sent over the Facilities Data Link (FDL) channel. Remote
Payload Loopback deactivation is supported via the payload loopback
deactivate request BOP 0x32FF being sent over the FDL.
Performance Monitoring Statistics Collection and Reporting is supported
on T1ESF lines, as described in section 9.4 of the ANSI T1.403-1995
standard. Statistics are collected every second. Statistics are reported, via
status MOPs on the FDL, to the central office switch once every second.
UltraWAN CSU/DSU connectors also support loopback activation and
deactivation via the console interface. In this case, in-band, BoP, or MoP
activation and deactivation requests are not used or recognized. Instead,
a loopback condition is forced on the connector from the Pathbuilder
software. Loopbacks support for both E1 and T1 lines is provided. This is
especially helpful for E1 lines, since no standards exist for in-band
activation and deactivation. See the LPBK command in Appendix H for
more detail on how to activate and deactivate a loopback from the
console.
Two performance statistics displays are provided to console users. These
displays contain the detailed statistics information specified in the AT&T
TR54016.
Although these statistics have been defined for reporting on T1 ESF lines,
the statistics information is available for both E1 and T1 lines. Once
again, this is especially helpful for E1 lines, since no standards exist for
in-band reporting of this information to the PTT switch.
The specific display parameters and commands are described next:
