6. REMOTE PROVISIONING AND
DIAGNOSTICS
Control Protocol
Remote access to provisioning and status information
is accomplished using ADTRAN Digital System 6
Message protocol, defined in Control and Diagnostic
Procedures Practice, Section 6032991-6. Digital
System 6 is supported by the TPI 108/109 and 105
portable test set and is supported by Hekimian React
2001 Release 1.900 remote test system. The IDSL
OCU-R network element complies with ANSI
T1.107-1995, “Digital Hierarchy Format
Specifications Annex G” which allows remote
provisioning, querying, and performance monitoring
via inband 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
inband 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 inband commands may be used to
verify options via dialogs with REACT 2001 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 indicator
Flashes during control link establishment and remains
ON after the IDSL OCU-R has been remotely
provisioned.
If the IDSL OCU-R has been remotely provisioned,
the operator can alternate between remote
configuration and manual switch settings by pressing
the momentary LBK button located on the front panel
for 5 seconds. If the IDSL OCU-R is removed from
the system, the unit retains previous provisioning
information in nonvolatile RAM.
The AP LED remains ON when the IDSL OCU-R is
operating based on Remote Provisioning, and is OFF
when operating on manual switches. See Table 5 for
LED indication.
7. MAINTENANCE
The T200 IDSL OCU-R does not require routine
maintenance for normal operation.
8. DEPLOYMENT GUIDELINES
The IDSL OCU-R allows a standard U-interface to be
used to provide DDS over a single pair. Listed below
are the loop design guidelines for deployment of DDS
over IDSL.
• All loops must be nonloaded.
• Actual Measured Loss (AML) should not exceed
40 dB at 40 kHz (135 Ω termination), the Nyquist
frequency of a U-interface.
• Total bridged tap length should not exceed 2 kft.
NOTE
If any of the above Deployment Guideline criteria
are not met, design should be considered using
Total Reach DDS, with the exception of the first
bullet.
