Latching Loopback Time out
Latching loopbacks created by either the
LBK
pushbutton on the TR OCU DP or the TR DDS-R
automatically release after 120 minutes, returning the system to normal operation.
Remote Provisioning and Diagnostics Control Protocol
Remote access to provisioning and status information is accomplished using the ADTRAN
Digital System 6 Message protocol, as defined in
the
Control and Diagnostic Procedures
Practice,
Section 6032991-6. Digital System 6 is supported by the TPI 108/109 and 105
portable test sets and is supported by the Hekimian React 2001 Release 1.900 remote test
system. The Total Reach DDS network elements comply with ANSI T1.107-1995, “
Digital
Hierarchy Format Specifications Annex G
,” which allows remote provisioning, querying, and
performance monitoring using in-band control of network elements.
NOTE
The REACT 2001 GUI software Release 1.900 supports ANSI
T1.107-1995. Remote access is accomplished using a defined set of
in-band DS0 byte sequences similar to the latching loopback
sequence. Commands issued through the test system are
recognized by the individual channel unit, which responds with the
appropriate byte sequences. These in-band commands can be used
to verify options by way of dialogs with REACT 2001, TPI 105, and
TPI 108/109 test sets. Unit CLEI, serial number, provisioning, and
performance information can be retrieved remotely using the
Digital System 6 protocol.
Provisioning and Status
All configuration options can be remotely viewed or provisioned. The front panel
AP
LED
flashes during control link establishment and remains
ON
after the TR OCU DP has been
remotely provisioned. If the TR OCU DP has been remotely provisioned, the operator can
alternate between remote configuration and manual switch settings by depressing the front
panel
LBK
pushbutton for five seconds. If the TR OCU DP is removed from the system, the unit
retains previous provisioning information in nonvolatile RAM. The
AP
LED remains
ON
when
the TR OCU DP is operating based on remote provisioning, and is
OFF
when operating on
manual switch settings. Refer to
on page 5 for LED indicators.
