System Introduction
Issue 3 June 2001
1-9
â– New features:
— Multiple OS Gateway Network Element (GNE). In DDM-2000/
SLC
-2000 networks, more than one NE can be physically connected
to X.25 allowing OSs to automatically select an alternate GNE in
case of primary GNE failure. The feature also allows different GNEs
to support different OSs simultaneously.
— Provisionable X.25 packet size of 128 or 256 bytes.
— Enhanced PM. Enhancements to DS1 and DS3 line and path PM to
further support tariff verification. Enhanced DS3 PM requires the
new BBG4B DS3 circuit pack.
— CPro-2000 R3.0, 4.0, 5.0, and 6.0.
Release 8.0 is a linear release using the new BBG8/BBG8B system controller and
BBG9 overhead controller circuit packs.
â– New applications:
— OC-3 operations interworking with FT-2000 OC-48 Lightwave
System. Single-ended operations and DCC connectivity supported
over OC-3 interfaces. Requires FT-2000 OC-48 Lightwave System
Release 6.0 software.
— OC-3/IS-3 linear extensions from OC-12 rings. 1+1 linear OC-3 and
IS-3 extensions from OC-12 rings.
— Increased subnetwork sizes. A DDM-2000/
SLC
-2000 subnetwork of
32 NEs. A mixed DDM-2000/
SLC
-2000/FT-2000 OC-48 Lightwave
System/OC-3 Release 7.2 subnetwork of 24 to 32 NEs.
â– New features:
— Multiple Operations System (OS) Gateway Network Element (GNE).
In DDM-2000/
SLC
-2000 networks, more than one NE can be
physically connected to X.25 allowing OSs to automatically select
an alternate GNE in case of primary GNE failure. The feature also
allows different GNEs to support different OSs simultaneously.
— Additional X.25 switched virtual circuits. Nine virtual circuits can be
provisioned in any combination of switched and permanent virtual
circuits for connections to OSs.
— Provisionable X.25 packet size of 128 or 256 bytes.
— Centralized operations over X.25 link. DDM-2000 CIT commands
have equivalent TL1 commands. This allows centralized operations
of DDM-2000 systems via the TL1/X.25 link as an alternative to CIT
commands.
