Description

SwitchCom Emergency Communications Bridge

Pervasive Telecommunications SwitchCom 100 system; a facility emergency telecommunications bridge that  will provide uninterrupted telephone service for your facility in the wake of natural and man-made disasters. 

When a wide-spread disaster leaves your phone systems inoperative due to land-lines and cell towers being down,  the SwitchCom 100 provides four or more channels of satellite telephone service to bring your facility back on-line,  providing backup communications for your mission-critical facilities when needed. 

At the heart of the SwitchCom system is the SwitchCom controller, a Linux/Asterisk-based telecom switch that allows integration with your facility's telecom system. Being Asterisk-based, the controller can be configured to 
be the facility telecom system. The standard configuration co-locates the controller and the satellite transceivers in the telecom closet. Designed into a 19-inch rack-mount enclosure, the controller will slide right into your telecom rack.

Optional External Weatherproof Satellite Transceiver Enclosure

The standard SwitchCom system co-locates the controller and the satellite transceivers in the telecom closet. However, to simplify wiring SwitchCom provides an optional weatherproof satellite transceiver enclosure, so you can mount them on the roof near the antennas. The controller in the telecom closet and the external enclosure are connected by a standard ethernet cable (and, standard 60 Hz. 120 VAC for the external box).

Roof Mounted Satellite Antennas

Each satellite channel requires one roof-mounted antenna. SwitchCom 100 Series base configuration includes four channels/four antennas, however any number of channels can be accommodated.

Product Description:

The SwitchCom 100 controller is an Open Source Software (OSS)  based telecom switch,  which has the flexibility to  allow integration with the facility telecom system.  Based on field-proven telephony software,  the Switchcom 100  can optionally be configured to be  the facility telecom system.

Because it is based on OSS, the SwitchCom 100 is “future-proofed” capable of being upgraded as technologies and needs change.

The SwitchCom can be configured in one of three different operating modes.

Fully-redundant mode – The SwitchCom can be configured to operate in a fully redundant mode, operating as a separate stand-alone telephone  system that is brought into use in an emergency.  In this configuration the system is furnished with its own set of telephone handsets so that it operates independent of and in parallel with the facility telecom system.

Mixed mode – The SwitchCom is configured by default to operate in a mixed configuration,  utilizing the existing PBX and phones in the facility to connect to the SwitchCom resources.  In normal use the facility’s PBX uses the landlines for outgoing and incoming calls,  and the SwitchCom is held in standby.  In an emergency scenario the outgoing and incoming calls are re-routed through the SwitchCom to allow the facility to have outside access.

 Full PBX mode – The SwitchCom can also optionally be configured to operate as the facility PBX.  In normal use landlines are used by the SwitchCom to connect the facility telephones to the outside world.  In an emergency scenario the landlines are bypassed and the facility telephones are routed through the Iridium network. 



The SwitchCom 100 can help assure seamless, persistent communications for your mission critical facilities.

The SwitchCom 100 will provide uninterrupted telecom communications for your facility in the wake of natural and man-made disasters.  When a wide-spread disaster leaves your telecommunications systems inoperative due to  land-lines and cell towers being down,  the SwitchCom 100 provides four or more satellite telephone links to bring your facility back on-line.  The SwitchCom 100 installs in your telecom closet, interfaces to your existing telecom technology, and stands by, continually assessing its internal health to assure that it is ready to provide backup communications for your mission-critical facilities when needed. 

The SwitchCom 100 system consists of several components,  the 4U 19-inch rack-mount controller,  the satellite transceivers,  and the antennas.   The antennas (1 per channel) are typically mounted on the roof with clear view of the sky.  The default  SwitchCom 100 configuration co-locates the controller and satellite transceivers in the telecom closet in a 4U rackmount chassis.  The SwitchCom 200 leaves the controller in the telecom closet and locates the satellite transceivers in a weatherproof enclosure on the roof near the antennas.

The SwitchCom 100 controller is an open-source software based telecom switch,  which has the flexibility to  allow integration with our existing facility telecom system.  Based on proven Private Branch Exchange software,  the Switchcom 100  can optionally be configured to be  the facility telecom system.

Input leakage current from line to ground will be less than 3.5mA rms. Measurement will be made at 240 VAC and 60Hz.

 

Redundant Power Supply Function

Redundancy

The redundant power supply is N+1=N (500W+500W=500W) function power supply, each one module is redundancy when any one module was failed. To be redundant each item must be in the Hot swap power supply module.

 

Hot Swap Requirements

The redundant power supply modules shall be hot swappable. Hot swapping a power supply is the process of inserting and extracting a power supply from an operating. During this process the output voltage shall remain within the limits specified in Table 7 with the capacitive load specified Table 9. The Sub-system shall not exceed the maximum inrush current as specified in section 2.2.

 

The power supply can be hot swapped by the following methods:

 

AC connecting separately to each module. Up to two power supplies may be on a single AC power source.

 

Extraction: The AC power will be disconnected from the power supply first and then the power supply is extracted from the sub-system. This could occur in standby mode or powered on mode.

 

Insertion: The module is inserted into the cage and then AC power will be connected to the power supply module.

 

For power modules with AC docking at the same time as DC.

 

Extraction: The module is extracted from the cage and both AC and DC disconnect at the same Time. This could occur in standby or power on mode. No damage or arcing shall occur to the DC or AC contacts which could cause damage. Insertion: The AC and DC connect at the same time as the module is inserted into the cage. No damage to the connector contacts shall occur. The module may power on or come up into standby mode.

Many variations of the above are possible. Supplies need to be compatible with these different variations depending upon the sub-system construction. In general, a failed (off by internal latch or external control) supply may be removed, then replaced with a good power supply(must use the same model) , however, hot swap needs to work with operational as well as failed power supplies. The newly inserted power supply may get turned on by inserting the supply into the system or by system management recognizing an inserted supply and explicitly turning it on.

 

LED Indicators

There is a single bi-color LED.
