OPTera Metro 3500 Multiservice Platform NTRN10AN Rel 12.1 Standard Iss 1 Apr 2004
Changing the BLSR configuration / connection audit period
A user can edit the BLSR configuration / connection audit period. The range
is between 15 minutes to 10080 minutes (7 days). The default is 1440 minutes
(1 day).
Channelized DS3 service (DS3VTx12 mapper)
The DS3VTx12 circuit pack accommodates 12 channelized DS3 signals,
demultiplexing each of them into 28 DS1s which are in turn mapped into
VT1.5s. As a result, each DS3VTx12 circuit pack gives full visibility and
access to 336 VT1.5/s.
In keeping with the commitment of OPTera Metro 3500 supporting full digital
cross-connect capabilities (DCS), users are able to cross-connect all and any
VT1.5s from the DS3VTx12 circuit pack to VT1.5 paths of any other kind
supported by this network element, such as OC-48, OC-12, OC-3, EC-1, DS1,
DSM, and other DS3VTx12s.
AINS, loopback, and manual facility provisioning are supported at both the
DS3 and DS1 facility levels. Full bandwidth management and In-Service
Traffic Rollover (ISTR) capabilities are supported at the STS-1 (DS3) level
down to the VT1.5 (DS1) level for the DS3VTx12 circuit pack.
The DS3VTx12 circuit pack supports some but not all performance
monitoring parameters that are supported on other DS3 and DS1 circuit packs.
Table 2-23 on page 2-108 and Table 2-24 on page 2-109 illustrate the
supported parameters on the DS3VTx12 circuit pack for DS3 and DS1 PMs.
Note 1: The DS3VTx12 mapper supports M13 and ASYNC mapping
only.
Note 2: VT management is supported with VTX-series circuit packs in
slots 13 & 14 only.
Note 3: The DS3VTx12 mapper is not supported on OPTera metro shelves
equipped with STX-192 circuit packs.
For more information about the DS3VTx12 mapper, see DS3VTx12 mapper
on page 3-90 .
Common Language Location Identifier
OPTera Metro 3500 supports an 11 character alphanumeric Common
Language Location Identifier (CLLI), that assigns a unique identification code
to each location and to each coded telephone plant item. The CLLI number is
user-provisionable and the code structure is: CCCCSSBBUUU
• CCCC is the geographical or place code
• SS is the geographical or state/country code
• BB is the network site code
