Appendix 3: Connecting the system to PRI/T1

Using CSU adapter

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).

Connecting to Adtran T1 ESF CSU ACE

Connect the PRI cable from the Codec to the input marked CPE on the Adtran CSU (straight through category 5 cable is recommended). Connect to the network via the NET connector on the Adtran CSU. When two Codecs are cascaded, connect the second Codec to the E1/T1 port 2 on the first Codec using a T1 crossover cable.
