tion mode the encapsulation must be set to 'hdlc' as well followed by configuring at least one timeslot per the
'timeslots' command.

Configuring HDLC CRC-Type
This command specifies the length of the checksum for calculating the CRC of the hdlc-frame. It can be either
a 16-bit or a 32-bit checksum.
Mode: hdlc
Step
[ name ] (hdlc)#crc-type {crc16 | crc32}

Configuring HDLC Encapsulation
The hdlc encapsulation command specifies what kinds of upper layer data are contained in the hdlc frames.
Two encapsulation types are available, framerelay and ppp. Once the hdlc configuration mode has been
entered, the procedure for setting up framerelay or ppp is exactly the same as for an X.21/V.35 serial port. For
that reason, see chapter 14,
ration and chapter 24,
"PPP configuration"
Mode: hdlc
Step
[ name ] (hdlc)#encapsulation {framere-
