E1 / T1 PRI (Primary Rate Interface) Telephony Interface Module
XR0052
The Xorcom PRI (Primary Rate Interface) telephony interface module (P/N XR0052) supports both T1 and E1 protocols. The hardware used in this module supports T1 CAS and E1 R2 as well.
Separate NT/TE connectors – no DIP switches or special cables required
LED status indication for each port including NT/TE status and layer 1 and 2 synchronization
Available in combined units with analog ports (see the “Astribank Telephony Interfaces Configurations” section on the Astribank page)
IP-PBX Integration
Each PRI telephony interface port has two connectors: one for TE and the other for NT settings, so no manual NT/TE setting is required. Status LEDs indicate active settings (TE or NT) and line status (no activity, layer 1 active, layer 2 active).
One PRI telephony interface module (with a half active PRI port – up to 16 channels) may be installed in a Spark CXS1000 unit.
One PRI telephony interface module (with a single active PRI port) may be installed in a C/XR2000 or C/XE2000 unit.
One PRI telephony interface module (with up to four active PRI ports) may be installed in a Blue Steel CXT3000/CXT4000, C/XR3000 or C/XE3000 unit.
Up to four PRI telephony interface modules (for a total of up to 16 PRI ports) may be installed in a single Astribank.
