3.5.36 ENT-CRS-VT1: Enter Virtual Tributary Cross Connection
This command creates a VT1 cross connect. When a UPSR cross connection is created, the path
presented by the first AID is configured to be the preferred path. For example, the first AID (f1) of the
cross connection (created by ENT-CRS-VT1::f1&f2,t1:123;) is the preferred path.
Notes:
1. The default cross connection type is 2WAY.
2. If a path is already in a connection, it cannot be in another connection even if the other is a 1WAY
and the new one will be 1WAY the other direction.
3. This command does not support creating multiple VT cross connections.
4. The UPSR VT cross connection can be created by using “&” in the AID fields of this command.
The following command is used to create a 1WAY selector or 2WAY selector and bridge with:
from points: f1, f2
to points: t1
ENT-CRS-VT1:[<TID>]:f1&f2,t1:<CTAG>::[<CCT>];

Input Format ENT-CRS-<STS_PATH>:[<TID>]:<FROM>,<TO>:<CTAG>::[<CCT>][::];
where:
• <FROM> indicates an identifier at one end of the STS cross connection and is
the AID from the “CrossConnectID” section on page 4-7
• <TO> indicates an identifier at the other end of the STS cross connection and is
the AID from the “CrossConnectID” section on page 4-7
• <CCT> identifies the cross connection type; valid values for <CCT> are shown
in the “CCT” section on page 4-23
Note A facility AID of FAC-{1-6,12-17}-{1-4} is allowed as the <FROM> or
<TO> portions of the cross connect for a G1000-4 card (ONS 15454). For
UPSR cross connections, the FAC aid should not be used in conjunction with
the “&” syntax, so <FROM> or <TO> AIDs such as “STS-1-1&FAC-5-1” or
“FAC-1-1&FAC-2-1” or “FAC-3-1&STS-2-1” should not be used. However,
if the <FROM> or <TO> AID uses multiple STS aids, then the other AID of
the cross connection can be a single FAC AID and
“STS-1-1&STS-2-1,FAC-5-1” and “FAC-5-1,STS-1-1&STS-2-1” are
allowed.
Input Example ENT-CRS-STS1:BODEGA:STS-5-1,STS-12-5:116::2WAY;
