6.6 Appendix 6 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 or equivalent
CSU, will allow up to 1.54 Mbps
connection. The E1/T1-interface
must be connected to a CSU
approved according to IEC
60950, UL 1950 or equivalent
standard. 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 system to the input marked CPE (Customer Provided
Equipment) 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 systems are cascaded,
connect the second system to the E1/T1 port 2 on the first system using a T1 crossover
cable.
Configuration of the system
Open the Administrator Settings Menu from the Control Panel and select Network.
Choose Network Type: PRI and specify your PRI number, max. Channels, cable length
(between system and CSU) and switch type.
Configuration of Adtran T1 ESF CSU ACE
Enter 2)CONFIG menu using SCROLL and ENTER buttons.
Enter 3)TERMINAL menu. Check 1)FORMAT:ESF, 2)CODE: B8ZS , 3)SET LBO: 0-
133 (corresponding to Cable Length setting on the system).
Go to main menu and enter 1)NETWORK menu. 7)SET LBO: 0.0 (according to
information from Telco).
Also, other network parameters should be set according to information from your
Telco.
Note! Cascaded connection: Remember to program numbers and MSN. Otherwise, the
first system will answer all calls.
