Table 6-1. DLT-CRS-VC Command Parameters
DLT-CRS-VC:[tid]:nt_vcl,lt_vcl:[ctag];
RESTRICTIONS: All parameters in this command are position-defined. This command
requires two AID parameter entries to uniquely identify an existing cross-connection. A
cross-connection must be place out of service before it can be deleted. A partial (PRTL)
response is generated if all cross-connections cannot be deleted. The range of values for
vpi and vci is determined by the number of VPI and VCI bits allocated.
[tid] Identification of the target NE. The default value is null. The NE SID
code is the only other valid value.
nt_vcl Virtual Channel Identifier for the Virtual Channel Link on the NT
(network) side. The value can be preceded with AID=, but this is not
required. Grouping and ranging are allowed. Enter in the following
format, replacing lower-case parameters with the values given:
NTVCL-vpi-vci
vpi: Virtual Path Identifier
vci: Virtual Channel Identifier for the Virtual Channel Link
lt_vcl Virtual Channel Identifier for the Virtual Channel Link on the LT (user)
side. The value can be preceded with AID=, but this is not required.
Grouping and ranging are allowed. Enter in the following format,
replacing lower-case parameters with the values given:
LTVCL-rack-shelf-slot-circuit-vpi-vci: ADSL interface
– rack: Rack number (1)
– shelf: Shelf number (1)
– slot: LT slot number (1)
– circuit: ADSL circuit on the LT (1−4)
– vpi: Virtual Path Identifier (for LT vpi=0, for NT vpi=0−15)
– vci: Virtual Channel Identifier for the virtual channel link (for LT
vpi=32−63, for NT vpi=32−1023)

with associated output responses. The default is 0.
