Circuit Source
Use the Circuit Source page to provision the overhead circuit source. Provisionable parameters include node, slot, port, and channel. Cards, ports, and channels that are fully utilized do not appear in the list. The following table describes the Circuit Source page fields and buttons that appear for overhead circuits.
 
Item
Description
Node
Sets the overhead circuit source node.
Slot
Sets the slot used by the overhead circuit. The card installed in the slot determines the availability of the Port fields.
Port
Sets the port used by the circuit. The Port field is not available if the slot chosen contains a multiport card.
Channel
The Channel field is available if you chose DCC Tunnel-D1-D3 as the tunnel type. Choose one of the following:
 •
DCC1 (D1-D3): RS-DCC
 •
DCC2 (D4-D6): MS-DCC, overhead bytes D4 to D6
 •
DCC3 (D7-D9): MS-DCC, overhead bytes D7 to D9
 •
DCC4 (D10-D12): MS-DCC, overhead bytes D10 to D12
