2.6Applications


This section describes how to apply TAINET Scorpio 1400 family in different network systems, which include cellular network, campus network and E1 network.

2.6.1Cellular network


T
he cellular network user will need to lease larger numbers of E1 circuits in order to connect remote cell sites to mobile telephone switching offices (MTSOs). TAINET Scorpio 1400 provides an alternative to standard repeater E1 service. Figure 2-1 shows a cellular network application.

2.6.2Campus network


The SCORPIO 1400 is well suited to the campus applications. Figure 2-2 and Figure 2-3 show two general campus applications where remote PBX or routers are interconnected across a campus using two SCORPIO 1400. One unit is configured as a central office site (CO) unit and the other is the customer premise equipment (CPE) unit.

Each Scorpio 1400 is configured at the factory to operate on the CO side of an E1 connection. However, you can easily modify settings intended for the CO into settings for CPE.


2.6.3E1 Network


The Scorpio 1400 can be deployed to replace traditional E1 network, without the repeater in the E1 network and effectively the utilization of the existing twisted copper pair.
