Dial Line

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

Table 9-4 shows each Dial Line configuration option as it appears on the LCD, with the Async Dial 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, a description of the available selections, and any equivalent AT commands.

Dial Line Configuration Options

Dial LineRate: 19200(V32t)

Nxt 19200(V32t) 16800(V32t) 14400(V32b) 12000(V32b) 9600(V32b) 7200(V32b) 4800(V32b) 2400(V22bis) 1200(V22) 1200(212A) 0–300(V21) 0–300(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.

19200(V32t), 16800(V32t), 14400(V32b), 12000(V32b), 9600(V32b), 7200(V32b), 4800(V32b) – The modem operates using V.32terbo, V.32bis, or V.32 modulation at the data rate selected. The modem can be forced by the remote modem to a lower data rate.

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 MNPt error control.

The factory default is 19200(V32t).

AT command for Dial Line Rate is S-register S41 = n, where n is:

1	= 14,400 (V.32bis)		7	= 1200	(V.22)
2	= 12,000 (V.32bis)		8	= 1200	(212A)
3	= 9600	(V.32bis/V.32)	10	= 0–300 (V21)
4	= 7200	(V.32bis)	11 = 0–300 (103J)
5	= 4800	(V.32bis/V.32)	20	= 19,200		(V.32terbo; default)
6	= 2400	(V.22bis)	21	= 16,800		(V.32terbo)

V32bis Automode: Enable

Nxt Enable Disable System 85

Enable – The modem automatically adapts to the modulation scheme and line rate of the remote modem. However, the maximum data rate the modem uses is determined by the Dial Line Rate configuration option. Bell 103J protocol is used for data rates of 0–300 bps.

Disable – Connection fails if the remote modem does not support the selected modulation.

System 85 – Modifies parameters used by the connection process. Specify System 85 only if your modem is in a modem pool attached to a System 85 Private Branch Exchange (PBX).

The factory default is Enable.

AT command is S-register S78 = n, where n is 0 for Enable,1 for Disable, or 2 for System 85.
