• The ShoreGear-T1 provides a single T1 PRI interface to the PSTN or legacy PBX
system.
• The ShoreGear-E1 provides a single E1 PRI interface to the PSTN or legacy PBX
system.
To determine the number of voice switches:
• Fill in the ShoreGear voice switches section in the Telephone and Trunk Planning
Spreadsheet (Figure 3-1 on page 3-5) to calculate the number of voice switches
required.
When you compute the user and trunk information in the spreadsheet, the
number of switches for each site is provided.
See Appendix A, “International Planning and Installation,” for more information about
which voice switches and features are supported in countries other than the United
States.
WAN Connections
To complete your system design, the final step is to identify your network connectivity.
You should identify the following for the network connections to each site:
• Bandwidth
• Latency
• Jitter
• Packet Loss
