Vanguard 7300 Applications
Multiservice IP,
SNA, Serial and
Voice Traffic
Figure 1-5 shows a Vanguard Series router used to support mixed IP, SNA, serial,
and voice traffic. To support this network environment the 7310 requires:
• T1/E1/PRI cards to support multiple T1/E1 interfaces to the Frame Relay or
IP Network
• T1/E1/PRI cards equipped with Voice Server PMCs to support packetized
voice and connection to the PBX/PSTN
• Serial cards to support connection of SNA/SDLC hosts and to interconnect to
Vanguard 6400s, which can be used to connect older, legacy devices
• 10/100BaseT Ethernet PMCs
Note that the Vanguard 7300 supports SNA/SDLC, and TBOP serial protocol traffic
along with Frame Relay, X.25, and so forth.
