Model 3611 Installation
3-53610-A2-GB41-60 March 1999
For the 6700 Series NMS, configuration options are
menu-driven. Select Config→Network→Devices→ the
appropriate submenu selection.
Tributary 3610 DSUs with TDM or MCMP can be
configured from an NMS provided the Position
configuration option (Diagnostic General) is set to Trib
from the SDCP and the DSU is connected to a control
DSU that is connected to the NMS.
The COMSPHERE 6700 or 6800 Series NMS, which
uses the Advanced Diagnostic protocol (ADp), fully
supports configuration of the DSUs with TDM and
multipoint dial backup or MCMP.
Configuration of the DSUs from an NMS using either
the DPII or DMC protocol is subject to the same
limitations identified in the COMSPHERE 3600 Series
Data Service Units, Models 3610 and 3611, User’s Guide
or the COMSPHERE 3600 Series Data Service Units,
Models 3610 and 3611, Operator’s Guide.
For more information on the matrix-coded format
and/or the NMS commands, refer to your NMS
documentation.
Verification Testing
Perform verification testing after any installation. After
installing and configuring a network, including control
and tributary DSUs, the DDS network and, if appropriate,
DBMs and their dial connections, perform the following
series of tests from the control DSU (using the SDCP or
an NMS) to verify network operation.
" Procedure
1. Request a device Identity (ID from the Status
branch) report from each tributary to ensure that
the DSU is addressed properly.
2. Perform a Digital Test (on the DDS circuit)
to ensure that the network is functioning. Refer to
the Digital Test section of chapter 5.
For a DSU configured for TDM mode, perform a
Digital Test on each active port.
For a DSU configured for MCMP mode, perform a
Digital Test on each tributary DSU on the
aggregate channel.
For a digital-sharing group, perform a Digital
Test on the lower-numbered port in the
digital-sharing group only.
NOTE
A control DSU can originate a
Digital Test in a point-to-point or
multipoint network. A tributary
DSU can originate a Digital Test
in a point-to-point network only,
provided the configuration
option Respond to Remote
Digital Loopback
(RespondRDL) is enabled in
the control.
For a DSU equipped with a DBM:
" Procedure
1. Select the Dial command to establish a dialed call
to the tributary to test for dial tone and verify that
the DSU can initiate and receive calls.
2. Select the →Dial command to switch the data to
the PSTN or switched 56 kbps circuit (enter Dial
Backup mode) to ensure that both DSUs have
been configured correctly.
3. Perform a Digital Test on both the DBM and the
PSTN or switched 56 kbps circuit.
For a DSU equipped with both DBM and TDM or
MCMP, perform a Digital Test on each of the
TDM or MCMP ports in Dial Backup mode on the
PSTN or switched 56 kbps circuit.
4. Drop the backup.
