Configuring Pseudowire Tunnels and Tunnel Groups
Each TDM service must include an encapsulation tunnel to determine how traffic over the service passes through
the network. In this version, encapsulation must use the MEF-8 protocol.
For PTP 820G and PTP 820F, You can configure up to 32 tunnels per unit.
Note
UDP/IP and MPLS support are planned for future release.
To configure TDM services with path protection, you must configure two tunnels for each protected service and
combine these tunnels into a tunnel group. For more information, see
Configuring a Tunnel Group .
