TL1/X.25 Interface
6
The DDM-2000 OC-12 Multiplexer supports a TL1/X.25 interface via a rear
access, synchronous, EIA-232-D port capable of speeds of 1200, 2400, 4800,
9600, and 19,200 baud to control and report alarm and status conditions and PM
data to an alarm surveillance OS such as Bellcore's NMA. This TL1/X.25 interface
provides detailed information such as identifying specific circuit packs and
facilities.
The TL1 maintenance messages of the DDM-2000 OC-12 Multiplexer are based
on Bellcore's TR-NWT-000833, Issue 3, Rev. 1, Issue 4, Supplement 1, and Issue
5, Rev. 1. The TL1 provisioning messages of the DDM-2000 OC-3 Multiplexer are
based on Bellcore's TR-NWT-000199, Issue 2, and TA-NWT-000199, Issue 6,
Supplement 1.
The DDM-2000 serves as the TL1/X.25 GNE for DDM-2000 TL1-RNEs.
DDM-2000 can now serve as the TL1/X.25 GNE for FT-2000 TL1-RNEs (as an
alternative to FT-2000’s existing capability to serve as the TL1/X.25 GNE for
DDM-2000 TL1-RNEs). ITM SNC (see following paragraph) or other vendor NEs,
such as Tellabs
TITAN, may also be the TL1/X.25 GNE for DDM-2000 TL1-RNEs.
The reverse is not necessarily supported; the DDM-2000 can not serve as a TL1/
X.25 GNE for Tellabs
TITAN R5.0.
The GNE serves as a single interface to the OS for the Lucent NEs in the same
Lucent 2000 Product subnetwork, using X.25 interfaces. The GNE receives
operations information from all the Lucent NEs through the DCC and reports this
information, as well as its own information, to the OS. The operations information
is in the form of TL1 messages. Through the GNE, the OS can send TL1
commands to any Lucent NE in the subnetwork.
The OS can use more than one NE as a GNE to provide redundancy and/or to
distribute TL1 message volume across multiple X.25 links. For example, two NEs
could each be connected via their TL1/X.25 interface to the same type of OS with
one GNE serving as a backup for the other.
Autonomous and command/response messages are also supported. Section 10,
"Technical Specifications," provides detailed specifications for the X.25 interface.
Detailed information about engineering a subnetwork with multiple DDM-2000
GNEs and the input and output parameters for TL1 messages is provided in 824-
102-151,
DDM-2000 Multiplexers Operations Systems Engineering Guide.
