7300’s
Figure 1-7 illustrates multiple Vanguard 7300 devices in very large networks. In 
this example, traffic is distributed across a numbers of Vanguard 7300’s for 
load-balancing and redundancy. Network connections are made via multiple T1/E1 
interfaces. 
The example shows redundant Vanguard 7330s, each connected to multiple 
applications. Note that each Vanguard 7330 has a voice connection to the PBX and 
an Ethernet connection to the host server.

Figure 1-8 shows an application in which a Vanguard 7300 Series router is used in 
large alternate carriers and small central office (CO) environments. The Vanguard 
7330 router, equipped with T1/E1/PRI cards with Voice Server PMCs, supports 
Public Switched Telephone Network (PSTN) voice applications.
