COMSPHERE 3600 Series Data Service Units
Network Management
The 3600 Series DSUs can be managed from both the
diagnostic control panel (DCP) or from an NMS.
Protocols
DMC – Diagnostic MicroComputer is the network
management protocol used by the Paradyne ANALYSIS
6510 Network Management System.
NMS Interface
The DSU provides three channels to carry diagnostic
information, such as Health and Status information and
test reports and results.

NMS connections.
The Control Channel (CC) is the connection between
the NMS and a control DSU. It operates at 1200 bps
asynchronous (or 110 bps for DMC).
The 3600 Series DSUs use three protocols to
communicate with the NMS, listed as follows:
ADp – Advanced Diagnostic protocol is the
network management protocol used by the
COMSPHERE 6700 Series NMS and 6800 Series
NMS.
DP II – DATAPHONE II protocol * is the network
management protocol used by the DATAPHONE II
family of AT&T NMS products (System Controller,
Diagnostic Console, and Network Controller) or a
COMSPHERE 6800 Series NMS.
* When operating in DPII protocol, the diagnostic configurations must follow DATAPHONE II rules (e.g., no
multipoint circuits can be extended off another multipoint circuit; a G2 tributary can have only one device on its poll list.

In-band Secondary Channel Transport provides
diagnostic communication between a control DSU and a
tributary DSU. The in-band secondary channel transport
can be configured for disruptive, nondisruptive, or mixed
communication. (Refer to the following section,
Secondary Channel
Transport, for further information.)
This feature supports up to 80 addresses for a DPII
protocol or up to 255 addresses for ADp.
The Diagnostic Channel (DC) provides
communication to extended circuits. The Diagnostic
Channel connects the backbone tributary of an extended
circuit to a control DSU
(Figure 1-4, Part
1200 bps asynchronous and supports up to 80 addresses
for a DPII protocol or up to 255 addresses for ADp. It is
not supported by a single port multipoint tributary DSU.
An additional extended diagnostic connection is shown
in
Figure 1-4, Part
D. In this case, the diagnostic channel
can be extended from a tributary Model 3611 DSU to
another Model 3611 DSU remote location using an NMS
adapter cable (feature number 3000-F2-510). For this
configuration, the remote Model 3611 DSU must be
configured as a tributary. The NMS adapter cable is
connected to Port 1 of the DSU (EIA-232-D); the SDU
must be strapped for a DC connection (S1-2 ON and
S1-1 Off).
NOTE
For a Model 3611 control DSU,
network management connection
is through the SDU. For a
Model 3610 DSU, a 3600
Hubbing Device is required for
NMS connection.
