Can any one tell me teh diffrence between those 3:

EXTERNAL-LINE-ISDN-NET
EXTERNAL-LINE-ISDN-USR
EXTERNAL-LINE-QSIG
 
Ericssonpro,

EXTERNAL-LINE-ISDN-NET, EXTERNAL-LINE-ISDN-USR,EXTERNAL-LINE-QSIG all use TLU76/1, but dig CAS route use a TLU76/3. The only difference between the two (and other TLU76 variants) is the EEPROM on the board (and the label on the front).
