AT-command set of the Eicon ISDN Port 55
Subaddress
If a subaddress (SUB) needs to be entered, it must be separated from the rest of the call
number by a vertical character [|] (also called the pipe symbol). The pipe symbol can be
typed directly from English keyboards, or by holding [Alt] down and entering [0], [1], [2],
[4] on the numeric keypad.
AT +iF <n> RNA-Framing (applies only to the RNA mode)
n = 0: No Framing check
n = 1: Force synchronous conversation
n = 2: Force asynchronous conversation
n = 3: Detect necessary conversation by analyzing incoming data
packets.
AT +iB <n> B-channel Data Rate for digital protocols
n = 0: Not Supported
n = 1: 600 bps
n = 2: 1200 bps
n = 3: 2400 bps
n = 4: 4800 bps
n = 5: 9600 bps
n = 6: 19200 bps
n = 7: 38400 bps
n = 8: 48000 bps
n = 9: 56000 bps
n = 10: 64000 bps
n = 11: 7200 bps
n = 12: 12000 bps
n = 13: 14400 bps
n = 14: 28800 bps
n = 255: Default (V.110: 38400 bps; others. 64000 bps)
Note: The supplied data transfer rates depend on the selected protocol:
V.110 syncron:
600 bps - 48000 bps
V.110 asynchron: 600 bps - 56000 bps
others: 56000 bps and 64000 bps
Some telephone switches in the USA only support 56000 bps. If there are
any connection problems with 64000 bps, you can reduce the data transfer
rate of the X.75, V.120, PPP and other digital protocols to 56000 bps. But
this has to be done on both sides of the connection (the calling side as well
as the called side).
