The Enterprise Telephony Management System (ETM), version 5.0.1, is a voice firewall and management platform that supports H.323, SIP, Tl-CAS,
ISDN-PRI and analog telephony traffic.
In this application, each Auditor Card terminates four D4 T1 trunks and originates four
ISDN-PRI trunks while supplying the required translation of signaling and call progress tones.
The sensor appliances are available in T1,
ISDN-PRI and 12-line analog versions.
PC-based RAS systems handle high-density remote access traffic from both T1-RBS (V.34, V.34 Plus) and
ISDN-PRI connections up to 64 Kbps per channel.
Depending on the number of LAN conferencing users, the WAN interface should be able to handle multiple
ISDN-PRI lines, and to grow easily as a user's needs evolve, Pignatello adds.
