Verilink Vendor
Number
A vendor number is a number that the SNMP Manager of Managers (MoM)
can use to isolate information about any vendor’s equipment for viewing.
For example, you might want to look at all the traps sent by Verilink
equipment.
Verilink’s vendor number is 1.3.6.1.4.1.321.1.1.
Verilink’s vendor number for the NCM card is 1.3.6.1.4.1.321.11
TABS-based and ACP-based Application Modules
The NCM uses both TABS (Telemetry Asynchronous Block Serial
protocol) and ACP (Advanced Communications Protocol) to control
application modules. TABS-based modules include the AS2000
legacy modules such as TAC and DIU cards. The NCM acts as a Node
Controller for up to four Multi-line shelves containing up to 51
application modules.
Enhanced
Feature Sets
The NCM enhances and expands the functionality of several ACP
modules:
• HDM 2180 and HDM 2182 DS3 DSU modules have increased
support for far end statistics and configuration when an NCM
manages the node.
• DPRI 2922 Dual Port Primary Rate ISDN modules are able to do
ISDN dialing with an NCM present. Without the NCM, the DPRI
2922 functions only as a T1 DSU, without dialing or dial
backup functions.
• The QPRI 2921 Quad Primary Rate Interface ISDN module
functions as an ISDN device only with an NCM. Otherwise, it
functions as a Dual CSU module like the DCSU 2911.
