HDLC service can be configured on the following ports:
16-port T1/E1 ASAP Adapter card on clear channel or fractional DS1 or E1 ports
32-port T1/E1 ASAP Adapter card on clear channel or fractional DS1 or E1 ports
12-port Serial Data Interface card on V.35 or X.21 serial ports (at super-rate speeds only)
HDLC ports can be configured in access mode to support Hpipes on the above cards. The encap-type must be set to hdlc.
HDLC encapsulation can be used on a port to transmit cHDLC frames into an Hpipe.
Use the following CLI syntax to configure a T1/E1 port for HDLC.
HDLC ports cannot be configured if the mode is set to network.
