Use the
and
keys to position the cursor
under the digit you want to change. Press F1 (Up)
to increment the digit or F2 (Down) to decrement
the digit. In this example, you would press
once to place the cursor under the middle digit in
the first digit field, then press F1 (Up) once to
change the
0 to a 1. Continue in this manner to
change the other digits.

Selecting the Link Layer Protocol
You have the option of selecting either PPP or SLIP as
the link layer protocol. PPP can be used for synchronous
or asynchronous operation. SLIP can be used for
asynchronous operation only.
The 3160/3164 implementation of PPP supports the
following:
• Full negotiation of PPP’s Link Control Protocol
(LCP).
• Active negotiation of LCP when the connection is
established.
•
Maximum Request Unit (MRU) sizes up to
1500 bytes, but the 3160/3164 DSU/CSU will
attempt to negotiate down to 500 bytes.
• The 3160/3164 DSU/CSU provides a unique LCP
magic number derived from the unit serial number
and the elapsed time.
• Full negotiation of escape characters.
Model 3160/3164 implementation of PPP does not
support Link Quality Reports (LQR), compression,
encryption, Password Authentication Protocol (PAP) or
Challenge Authentication Protocol (CHAP).
Model 3160/3164 implementation of SLIP supports a
fixed MRU size of 1006 bytes.
Before selecting the protocol, you must first select the
port to be used as the communications link. Refer to the
Selecting the Port section earlier in this chapter. This
example assumes that the MODEM port is being used as
the communications link.
To select the link layer protocol,
