Cisco HDLC monitors line status on a serial interface by exchanging keepalive request messages with peer
network devices. It also allows routers to discover IP addresses of neighbors by exchanging Serial Link
Address Resolution Protocol (SLARP) address-request and address-response messages with peer network.
Only IES SAPs (including SAPs in VPRN service) can provision a Cisco-HDLC-capable configuration.

Description
This command configures the clock to be used for transmission of data out towards the line. The options are
to use the locally recovered clock from the line's receive data stream, the node central reference, or an
adaptively recovered clock using the received packets.
The following tables show MDAs that support loop timing at DS3/E3 and DS1/E1 channelization options.
