• T.30 fax protocol support
• T.38 fax-over-IP protocol
• V.21 channel 2 binary signaling modulation and demodulation
• High-level Data Link Control (HDLC) framing
• V.27 term (2400/4800 bps) high speed data modulation and
demodulation
• V.29 (7200/9600 bps) high speed data modulation and demodulation
• V.17 (14390 bps) high speed data modulation
• V.21 channel 2 detection
• Multi-channel operation support
Note: If two ends support T.30 protocol, they are compatible only if
external factors (for instance, delay and signal quality) permit. Only ITG
node to ITG node fax calls are supported (although Meridian 1 to
third-party fax calls may work).
Remote Access
Remote Access is supported on the ITG. Remote Access allows a MAT user
with no ITG data, including Nortel Networks support personnel, to manage
the ITG ISL Trunk card remotely.
Management and support of the ITG network depend on IP networking
protocols including SNMP, FTP, and Telnet. The Nortel Networks Netgear
RM356 modem router or equivalent should be installed on the Meridian 1 site
management and signaling LAN (called the embedded LAN or E-LAN as
opposed to the customer's enterprise network or C-LAN) in order to provide
remote support access for ITG and other IP-enabled Nortel Networks
products.
The Nortel Networks Netgear RM356 modem router integrates the functions
of a V.90 modem, a PPP remote access server, an IP router, and a 4-port
10BaseT Ethernet hub, and provides a range of security features that may be
configured so as to comply with the customer's data network security policy.
