2.4 ISDN leased line (option)<br />
With a special firmware generation the TA+USBA supports the connectivity of an<br />
ISDN leased line (type 64S, or 64S2).<br />
To use the TA+USBA on an ISDN leased line you have to configure the firmware<br />
especially.<br />
This chapter includes the special settings for the leased line configuration only.<br />
The following parameter must be set<br />
**ISDN<br />
Select D channel protocol<br />

running on the ISDN line otherwise a connection cannot be set up.<br />
Note: after changing and storing the ISDN protocol the TA has to be reset by<br />
powering it off and on (alternately you can use the command<br />
AT&W**RESET).<br />
AT**ISDN=12 Select LL 64SB1 (leased line 64S, B-channel 1)<br />
AT**ISDN=13 Select LL 64SB2 (leased line 64S, B-channel 2)<br />
AT**ISDN=14 Select LL 64S2 (leased line 64S2, B-channel 1)<br />
