Communications Server
Commserver Types
The Communications server comes in three different variants:- Modem bank, each modem addressable on a decicated TCP port
- Multi-channel IP router to access the internet over 8 channels
- Stand-alone GPRS/HSDPA core networks data tester
Flexibility
Whether used as a failover communications device, a super broadband bandwidth router, an industrial modem bank or any of the other applications, the flexibility of the Communications Processor allows for powerful functionality and integration options.Mission-critical Communication
You need your wireless connectivity to be reliable. You know how fickle a consumer modem can be when used in a server or unmanned environment. The Communications Server's natural habitat is in a 19" rack and was developed to be ultra-reliable whilst working hard for you. Points of failure are reduced by component overspecification during the design process.Applications
Just some of the applications of the Communications Server include:- Access each modem directly via a TCP connection over ethernet
- Multi-APN access with diverse or dedicated routing paths per APN
- Primary or secondary communications channel for a corporate environment
- Failover between different GSM networks
- Splitting communication types such as internet, email and corporate traffic across different APN or even different networks
- 8-Channel modem bank with TCP/Ethernet interface for high volume bulk SMS, USSD or Data
More about the variants:
In Modem Bank mode, the commserver can be used to easily access all 8 modems from an appliction using TCP sockets. Each modem resides on a different TCP port (e.g. port 3001-3008). To address the first modem, you make a TCP connection to the commserver IP on port 2001. There are also management port that allow you to remotely reset a specific or all modems with a single command.
In Router mode, the commserver acts as a standard GPRS/HSDPA router
for Internet access, the only difference is that it will use 8 channels and
route-balance outbound connections across the available channels (up to 8) to
ensure a fairly even use of all 8 on-board modems.
In Data Testing mode, the commserver is loaded with an autonomous
software image that will test the effectiveness of the GPRS network by
measuring attach rate successes, APN authentication successes and
connection rate successes. It will also regularly poll predefined sites
by downloading test files and graphing all the success/failures and
throughput on the network.
