TL1 Commands
3.5.34 ED-VT1: Edit Virtual Tributary
This command edits the attributes associated with a VT1 path.
Both RVRTV and RVTM parameters only apply to UPSR.
The TACC parameter edits an existing single STS or VT and changes it to a test access path. When an
editing command on TACC is executed, it assigns the STS for the first 2-way connection and STS=1 as
the second 2-way connection.
Error conditions:
1. Sending this command to edit RVRTV or RVTM for the non UPSR VT path, an error message will
be returned.
2. If sending this command to edit both TACC and any other attribute(s), the (Parameters Not
compatible) error message will be returned.
3. This command is only allowed whenever there are no circuits/cross connections (no UPSR
connections) on that AID.
4. If sending this command to edit TACC on an AID with circuits or cross connections, or if the
port/VT has a TAP, an error message (VT in Use) will be returned.
5. TACC creation will also be denied on the protect ports/cards.

[TACC=<TACC>];
where:
• <AID> is the access identifier from the “VT1_5” section on page 4-17 and must
not be null
• <RVRTV> identifies a revertive mode which only applies to UPSR; valid values
for <RVRTV> are shown in the “ON_OFF” section on page 4-51 and <RVRTV>
is optional
• Valid values for <RVTM> are shown in the “REVERTIVE_TIME” section on
page 4-55
• <TACC> defines the STS as a test access path with a selected unique TAP
number. The TAP number ranges from 0–999. When TACC is 0, the TAP is
deleted. <TACC> is an integer.
