RAD Data Communications, Inc.24 Channel Statistical MultiplexerSTM-24
Description
FEATURES
Multiplex statistically 8, 16 or 24 async channels onto a single sync link
Asynchronous channel data rates up to 19.2 kbps
Composite link data rate up to 64 kbps
Composite link interfaces: V.24/RS-232, V.35, X.21 and RS-530
Independent hard and soft flow control for each channel
Control signal passed end-to-end, bi-directional
Menu controlled configuration and diagnostics
Downloading of system parameters
Permanent storage for system parameters
Password secured access
The STM high speed statistical multiplexers, integrate up to 24 asynchronous channels onto a single synchronous link. Three models are available:
STM - 8 with 8 asynchronous channels
STM - 16 with 16 asynchronous channels
STM - 24 with 24 asynchronous channels.
The channel data rates are from 75 bps up to 19.2 kbps. The synchronous composite link operates at up to 64 kbps and has four selectable interfaces:
V.24/RS-232
V.35
X.21
RS-530.
Powerful error detection and automatic retransmission ensures error free performance.
The STMs feature independent hard and soft flow control for each channel. End-to-end flow control can be initiated from DTE to DTE or from the STM channel to the remote DTE. Several characters for X-ON and X-OFF are provided, enabling compatibility with most applications.
Any sub-channel can be used as a command port to configure the entire system or to perform diagnostic tests. Password secured access prevents unauthorized alteration of the system configuration.
The STMs feature permanent storage of the user-programmed system configuration, using non-volatile memory and downloading of the configuration parameters.
Comprehensive diagnostic capabilities provide local and remote loopbacks on the sub-channels or on the composite channel, as well as testing of the modems between two STM units.
The STMs are designed for desktop or 19" rack installation. Sub-channel connections are made via RJ-45 connectors located on the front panel.
The STMs can be connected to RAD's APS and SPS packet switching products for expanding the number of async channels in PAD/FRAD applications
