MIDAS 4.X NMS Configuration , Rev. 6
Introduction to MIDAS NMS 1–7
Node
A MIDAS network node:
Provides the interface for user traffic
Manages local resources in cooperation with the NMS
A node can be located at a remote site, or at the NMS site. Multiple nodes can
be located at a remote site and share the RF equipment. As stated previously,
one or more nodes located at the NMS site can share the RF equipment.
Node Components
A MIDAS node may consist of:
SNM-1000 Node Control Modems, each controlling from 1 to 30 traffic
modems
SNM-1010/1010L Data Control Modem, which serves as both the node
control modem and traffic modem

The SNM-1000 Node Control Modem performs as a dedicated node
controller. At a traffic node, it provides the interface to the NMS and manages
local resources under NMS control. It executes circuit setup and termination,
provides local M&C and diagnostics, and reports call detail information to the
NMS.
The SNM-1000 can manage up to 30 data modems.
For detailed information on the SNM-1000 Node Control Modem, refer to the
SNM-1000 Node Control Modem Operation and Maintenance Manual.

The SNM-1010/1010L Data/Control Modem provide both control and traffic
functions, switching between the two modes as required. They are used at sites
that require single-channel data connectivity.
In control mode, the SNM-1010/1010L provides the interface to the NMS.
The modulator (operating in burst mode) is tuned to the inbound control
channel; while the demodulator (operating in continuous mode) is tuned to the
outbound control channel.
To originate or receive a call, the SNM-1010/SNM-1010L switches to traffic
mode. While carrying user traffic, the modem operates in continuous transmit
and receive mode. It supports data rates from 2.4 kbps to 5.0 Mbit/s.
