Appendix 3: Connecting the system to PRI/T1

Connecting the system to the ISDN network via the E1/T1-interface using an Adtran T1 ESF CSU ACE will allow up to 1.54
Mbps transmission. The E1/T1-interface must be connected to a CSU approved according to IEC 60950, UL 1950 or
equivalent standard.
NOTE: The PRI-line will run the AT&T 4ESS, 5ESS and National ISDN protocols in addition to Euro ISDN (E1).
