Configuring Cross Connections
Use the Configuration - Cross Connect screen to establish or delete Virtual
Channel Connections (VCCs) by port or by slot. Connections may be established
between any combination of:
Subtended ports
DSL ports
Network interface (uplink)
Default Mappings
A DSL port’s data VPI/VCI is always 0,35.
Default VC mappings to the SCP card for data service may be determined so:
VPI is 2 for ports 1–24 and 3 for ports 25–48
VCI is (Slot * 24) + (Port number up to 24) + 7
Port numbers 25 through 48 are reduced (by 24) to 1 through 24, respectively, in
calculating VCI. So the VCI for Slot 3, Port 1 is the same as the VCI for Slot 3,
Port 25:
Slot 3, Port 1: 3*24 + 1 + 7 = 80
Slot 3, Port 25: 3*24 + 25 – 24 + 7 = 80
