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

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.
