Page 26: Ii.10. Isdn Adaptor - Ia12, Exp-Ia12
The IA12 ISDN Adaptor is an ETSI compatible terminal adaptor that serves as an interface between the ISDN BRA-S0 lines coming through the network terminator (NT1) of PTT and the analog lines of the MS48 system. The adaptor also supports many EURO-ISDN facilities for Basic Rate Access. - Page 27 NT1, two 623K4 type connectors for connection to the A / B terminals of the analog line on the MS48 system and one 6-pin RJ jack for connection to the data line of KAREL telephones. The data cable having a connection box at one end and a RJ45 plug at the other end also comes with the adaptor.
- Page 28 These network messages are also transferred to the CRL accessories. Neither MS48 system nor IA12 ISDN Adaptor has internal S0 ports, so it is not possible to connect an ISDN terminal to the extensions of MS48 system. However, it is possible to connect another ISDN terminal in parallel with the IA12 ISDN Adaptor in the Point to Multi-Point lines with MSN facility.
