7. Press F1 (Next) until the Com IP Adr
configuration option appears.
NOTE
Steps 8 and 9 describe the
process for entering an IP
address. This process applies to
any IP address.
8. Press F2 (Edit) to edit the IP address. You have the
option of using F3 (Clear) to reset the IP address
to the factory default 000.000.000.000.

9. 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
Two link layer protocols, Point-to-Point Protocol (PPP)
and Serial Line Internet Protocol (SLIP), are supported for
connection to an external SNMP manager, Telnet device,
or network device (e.g., a router). PPP can be used for
synchronous or asynchronous operation. SLIP can be used
for asynchronous operation only.
NOTE
The carrier-mounted DSU/CSU
does not support synchronous
operation on the COM port.
The standalone DSU/CSU 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 DSU/CSU will attempt to
negotiate down to 500 bytes.
•The DSU/CSU provides a unique LCP magic
number derived from the unit serial number and the
elapsed time.
•Full negotiation of escape characters.
The DSU/CSU implementation of PPP does not
support Link Quality Reports (LQR), compression,
encryption, Password Authentication Protocol (PAP) or
Challenge Handshake Authentication Protocol (CHAP).
The DSU/CSU 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 on page 3-14. This example
assumes that the COM port is being used as the
communications link.
