Provisioning a DS3E Card in CTC Using TL1
1.5 Provisioning a DS3E Card in CTC Using TL1
The DS3E card can autosense the framing being received and set the framing accordingly; however, this
framing autosense feature can only be set using CTC. Use CTC to set the FMT attribute on a DS3E card
to autoprovision which results in the FMT field being blanked out for a few seconds while the DS3E card
is determining the framing mode coming into that particular port. The FMT field is then set accordingly
to unframed, M23, or CBit. If the DS3E card is not present (pre-provisioned), setting the FMT field to
autoprovision will result in the FMT field defaulting to unframed.
The TL1 interface does not support the autoprovision option for the DS3E card; the TL1 interface only
supports unframed, M23, or CBit. If autoprovision is selected from CTC and at the same time the TL1
command RTRV-T3 is issued, the TL1 output will result in the FMT field populated with unframed
during the time period that the DS3E card (if present) is autosensing the frame format. If the DS3E card
is not present (pre-provisioned), issuing RTRV-T3 after CTC sets the FMT to autoprovision will result
in the TL1 output populating the FMT field with unframed.
1.6 Mixed Mode Timing Support
Although mixed mode timing is supported via TL1 in this release, Cisco strongly advises against its
implementation. Mixed mode timing is not a recommended timing mode because of the inherent risk of
creating timing loops. Refer to Telcordia document GR-436-CORE, Digital Network Synchronization
Plan for recommended synchronization planning. Refer to the Cisco ONS 15454 Procedure Guide or the
Cisco ONS 15327 User Documentation for information about setting up ONS 15454/15327 timing. For
further assistance contact the Cisco Technical Assistance Center (TAC) at www.cisco.com or call
1-877-323-7368 for unresolved problems.
1.7 TL1 Command Completion Behavior
1.7.1 General Rules
Note The command completion behavior does not apply to RTRV-CRS, RTRV-ALM, and RTVR-COND
commands.
1.7.1.1 Explicit List of AIDs - No Wildcards
If a set of AIDs is explicitly listed, including a set of just one AID, then each AID must complete
successfully to return a CMPLD message. If more than one AID is in the set and at least one AID
succeeds but all do not, then a PRTL with errors for each failed AID is returned. If all AIDs in the set
fail, a DENY with errors for each failed AID is returned.
