B-3

Whatever local-remote address pair you assign at one end of a point-to-point

synchronous line, you reverse on the Version 5 router at the opposite end of the

line. For example, the synchronous circuit on Router A in Figure B-1 has an

explicit local address (LA) value of 0x04 and a remote (destination) address (RA)

of 0x05. In this case, you conﬁgure the synchronous circuit on Router B at the

opposite end of the same line with a local address (LA) value of 0x05 and a

remote address (RA) value of 0x04.

The Version 5 Conﬁguration Guide

• States correctly that you should not use the well-known DCE and DTE values

0x01 and 0x03 for any explicit local or remote address on a point-to-point

circuit

• States erroneously that the local and remote address values are decimal rather

than hexadecimal numbers

On Version 10.0 routers, you use the Version 4.0 Conﬁguration Manager and

follow essentially the same guidelines for local-remote address pair assignments

at each end of a point-to-point synchronous line. The Conﬁguration Manager

allows you to choose 0x02, 0x04, 0x05, 0x06, and 0x07 as (1-byte) explicit values

for Local Address or Remote Address in the synchronous line parameters window.

(You can extend an explicit local or remote address value to 2 bytes in length by

enabling the Extended Address parameter under the Sync circuit line parameter

group.)

The Version 10.0 Technician Interface imposes no constraints on the values you

choose for the local-remote address pair.
