System Introduction
1-8
Issue 3 June 2000
Release 3.0 (TARP Release)
supports the following features:
■
Pointer Justification Count (PJC). This performance monitoring parameter
indicates a frequency error in the network or other potential
synchronization problems. It provides a threshold crossing alert (TCA)
when the STS-1 pointer justification count in a performance bin exceeds a
user provisioned threshold value.
■
The BBF3B DS1 PM Circuit Pack low-speed interface can be provisioned
for the following DS1 formats: clear channel (default), superframe (SF) as
specified in
ANSI
T1.403-1989, or extended superframe (ESF) as specified
in
ANSI
T1.403-1989. In the case of SF or ESF format selections, DS1
performance information is collected by monitoring the associated DS1
framing format.
■
Single DS1 facility loopback using the BBF3B circuit pack.
■
Manual timing pack switch for the wideband shelf: This capacity adds the
ability to manually switch which main OLIU is supplying timing to the shelf.
In this way, the switch can be effected remotely. An additional use of this
capacity is to switch timing functionality off of a main OLIU prior to
removing it for maintenance. This feature also causes an “active-fn” OLIU
pack equipment switch which will be reflected in the “
rtrv-state-eqpt
report”.
■
Multi-Vendor Operations Interworking (OI) compatibility.
— DDM-2000 FiberReach is compatible with any other-vendor NEs
that support Target ID Address Resolution (TARP) protocol, OSI,
and TL1/X.25 as specified in Telcordia Technologies TR-253.
— Compatible with Tellabs
TITAN
5500/S Release 5.0 Digital Cross-
Connect System, including TL1 OS access with TITAN 5500/s DCS
serving as the TL1/X.25 GNE.
■
Lucent 2000 Product Family OI compatibility.
— Compatible with DDM-2000 OC-3 Release 13.0 and OC-12 Release
7.0 and FT-2000 R8.0 (but not with earlier releases due to multi-
vendor OI support).
■
Large subnetworks.
— Supports large subnetworks of up to 256 NEs by partitioning the
subnetwork into multiple areas connected via Level 2 Intermediate
Systems (IS).
■
CPro-2000, ITM SNC support. FiberReach Release 3.0 is supported by:
— CPro-2000 Release 7.0; ITM SNC Release 5.0.
