Setting the HDLC Service Type
The logical line HDLC service is LLC1 by default. LLC1 adds the HDLC address
and control fields as a prefix to the frame. You can change the service to basic
HDLC (transparent), based on the requirements of the E1 equipment.
Using the BCC
To set HDLC service, navigate to the logical-line prompt (for example,
stack
;
mce1/1/2/1
;
logical-line/mce1-121-1
) and type:
hdlc-service
variable
For example:
logical-line/mce1-121-1#
hdlc-service transparent
Using Site Manager
See the Service parameter on page A-37 for information.
Setting the Local HDLC Address
Use the options listed in Table 7-14
to specify the 1-byte HDLC address of this
logical line.
Use unique HDLC addresses for the local and remote interfaces at either end of
the point-to-point circuit. For example, if the remote address is DTE, configure
the local address as DCE.
If you configure X.25 on this line, set this parameter to either DCE or DTE.
