Dial Line Ð Singleport Mode A

The Dial Line configuration options are used to configure the modem for operation over dial lines.

Table 4-10 shows each Dial Line configuration option as it appears on the LCD, with the Sync Leased factory default setting (the default value if the modem is just being installed) shown following the colon ( : ) on the first line and with all available selections listed on the second line. Following this is a description of the configuration option. Factory default settings are listed in Appendix F.

Dial Line Configuration Options Ð Singleport Mode A

Dial Modulation: V34

Dial Modulation. Modulation reduces the amount of scrolling necessary to select Dial Line rates by limiting the number of Dial Line Rate configuration options. Only one group of Dial Line rates is displayed depending on the setting of the Dial Modulation configuration option (V.34, V.32bis, V.32 terbo, V.21, V.22, V.23, Bell 212A, and Bell 103J).

Dial Line Rate. This configuration option determines the modem's data rate and modulation scheme for operation on dial lines. Online changes do not take effect until a disconnect occurs.

NOTE: Certain changes to this configuration option will cause the modem to reset.

2400(V22bis), 1200 (V22), 1200(212A) ± Modem operates using the modulation and data rate selected.

0±300(V21), 0±300(103J) ± Modem operates in full-duplex, Asynchronous mode. These data rates do not support V.42 or MNP error control.

1200/75(V23), 75/1200(V23), 600/75(V23), 75/600(V23) ± The modem will run in asynchronous semi-full duplex mode at the rate chosen.
