SHRM03b - TDM 4U Managed 16-Slot G.SHDSL.bis TDM Chassis
The SHRM03b-CH chassis is a 4U 19 (23)" rack that supports dual power and 16-slot for 2 wires dual channels, 4 wires single channel hot swappable cards for G.703 E1, T1, V.35 (RS-530/449/X.21) and bridged Ethernet. Utilizing industry standard SNMP protocol, the management feature can configure and monitor each local channel and the connected remote modems. All the SHRM03b TDM chassis power supplies are hot swappable and modular, installing two into a chassis, provides redundancy should a single power supply fail.
A fully loaded chassis can run continuously with only one power module fitted into the chassis. The cooling fan unit is an optional component. In a stacked chassis scheme, where ambient temperature may be higher than 25C (77F), or the chassis is fully loaded with line cards, the fan option is recommended to keep cooler air moving through the chassis. The fan box is designed to be placed on top of the SHRM03b chassis and pulls warm air up and out of the chassis, expelling it out the rear of the fan box. The cooling fan unit will add 1U rack space to the chassis for an overall total of 5U. The SHRM03b TDM chassis has been designed as a Managed platform. This allows network administrators to deploy the chassis in a wide range of network. Technologies supported by the chassis included E1, T1, Data (V35/X21/RS530), and 10/100Base-TX Ethernet.

The SHRM03b-TDM chassis is supported with a family of G.SHDSL TDM based modems for use by carriers and SME users including the:
- SHDTU03-E1 which offers an ITU-T G.703 DTE interface which works over an SHDSL interface.
- SHDTU03b-Data which offers a V.35 DTE interface which works over an SHDSL interface.
- SHDTU03-ET100 which offers a 10/100Base-TX interface which works over an SHDSL interface and
- SHDTU03b-31 which offers three DTE I/Fs (E1, V.35, and Ethernet), which can work simultaneously to share DSL bandwidth.
- SHDTU03b-31T which offers three DTE I/F's (E1/T1, V.35 and Ethernet), which can work simultaneously to share DSL bandwidth.
In addition, RS-232 console and Telnet provide menu based management while embedded Web offers a user friendly graphical environment for OAM&P. This Rack is 100% compatible with our SHDTU03b standalone TDM based CPE modems for E1, serial data and Ethernet.
