Flow Control Hardware
From a terminal server, since you cannot press display buttons, modem-style AT commands must be issued
for all functions.
Since these commands apply to B-channels, you need to understand which B channel numbers apply to which
physical U interface (Table 4).
Table 4: Conguring the ISDN Simulator via Terminal Interface
BRI physical interface First B-channel number Second B-channel number
Port 1 0 8
Port 2 1 9
Port 3 2 10
Port 4 3 11
Port 5 4 12
Port 6 5 13
Port 7 6 14
Port 8 7 15
Once you understand the logical numbering, you can complete the commands (Table 5). The “x” parameter in
this table refers to the BRI channel number in Table 4.
Table 5: Conguring the Simulator via Terminal Interface, where “x” is the B-channel number
Function Additional Parameters Command
Get Phone number on B-channel “x”
“x” is the B-channel number from 0 to 15
ATNx?
Get SPID number on B-channel “x” ATPx?
Set Phone number on B-channel “x” ATNx =”value”
Set SPID number on B-channel “x” ATPx =”value”
Get/Set switch type
(in concert with SPID settings):
0 = either NI-1 or Net3
- NI-1: SPID set
- NET3: no SPIDs (””)
64 = 5ESS (SPIDs optional)
512 = DMS-100
