Cisco PGW 2200 Softswitch Platform
Table 1-1 shows the limitations of the WAN implementations.
Ethernet Connections
Each Ethernet NIC for each Cisco PGW 2200 Softswitch is connected to a switch through a 100BASE-T
interface. The switches connect to the SS7 interfaces through 10BASE-T or 100BASE-T interfaces.
Figure 1-1 displays the Ethernet connections between the elements of the Cisco PGW 2200 Softswitch

Condition Requirement
Software release version Cisco PGW 2200 Softswitch software 9.3(2) or later
(with associated operating system and hardware
requirements).
Total end-to-end delay, one way (the time
required to send a message from a source
to a destination, such as from a Cisco PGW
2200 Softswitch to a Cisco ITP-L)
Must be less than 150 milliseconds.
Packet loss (defined as missing packets
with a message)
Must not exceed 1 percent (preferably, less than 0.5
percent).
Note For packet loss rates below 0.5 percent, increase
the RUDP receive window size
(*. rudpWindowSz) to 64 to improve
performance.
Dual-VLAN SIP automatic switchover
support is enabled
Both Cisco PGW 2200 Softswitches should be part of the
same IP subnet.
