Network Management (AT
*
NE)
The 3460 Modem offers an in-band secondary channel for network
management commands, so you can configure modems while data
transmission continues.
Secondary channel mode functions only between 3460 Fast’R modems
with Release 2.0 or higher software. It is not compatible with other
Motorola modem secondary channel modes or competitor modem
secondary channel modes.
The AT
*
NE command controls secondary channel operation.
• Zero (0) enables the secondary channel. This is the default option.
• One (1) disables the secondary channel.
You can enable and disable the secondary channel through the AT ACU,
Fast’RVu (Commands menu), or an NMS. The option is saved in
non-volatile memory.
Secondary-channel communication is available when both modems are
in the following modes:
• V.34 modulation mode (at any primary-channel data rate)
• V.32 modulation mode, except 4.8 KBPS
• Direct, Normal, V.42, MNP, and LAPM data modes, with or
without data compression
Secondary-channel communication is not available during LAL, LAL
pattern, and DBER tests.
