The following warning applies in New Zealand:
Warning
This equipment does not fully meet Telecom’s impedance requirements. Performance limitations
may occur when used in conjunction with some parts of the network. Telecom will accept no
responsibility should difficulties arise in such circumstances.
Network Protocols Supported
The analog modems described in this chapter support the following protocols:
•
All standard data rates from 300 bps to 33.6 kbps (V.34
bis
)
•
V.42
bis
and Microcom Network Protocol
(MNP) 5 data compression
•
V.42, Link Access Procedure for Modems
(
LAPM), and MNP 2 to 4 error correction
•
MNP 10 for high performance under all line conditions
•
MNP 10EC for high performance in analog cellular environments
8- and 16-Port Analog Modem Network Modules, Version 2
The following analog modem network modules originate or terminate analog telephone transmissions
through RJ-11 modular jacks:
•
8-port analog modem network module (NM-8AM-V2) (see
Figure 10-3
)
•
16-port analog modem network module (NM-16AM-V2) (see
Figure 10-4
)
Caution
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety,
connect the 16-port analog modem network module (NM-16AM-V2) only to intra-building or
non-exposed wiring or cabling. The intrabuilding cable must be shielded and the shield must be
grounded at both ends.
