Network Requirements and Preparation WAN Technology Choices

WAN Technology Choices
Minimum Bandwidth Requirements
The minimum WAN bandwidth required to deploy a voice switch at a site depends on the number of
calls expected. With ADPCM, a single call consumes 52 Kbps, and if this call becomes a conference
call, another 52 Kbps is needed, yielding a total of 104 Kbps. From a broadband perspective, the first
available technology is 128 Kbps (ISDN), which leaves only 24 Kbps for other IP traffic. For
teleworking applications, where only a single call is needed, 128 Kbps can be used. For other sites on
the voice network, the minimum bandwidth recommended is 384 Kbps.
Various technologies, as shown in Table 14, are available from different service providers to provide IP
connectivity between locations.
Leased T1
Leased T1 facilities are the most robust WAN technology available. Leased T1s are point-to-point links
that inherently meet the network requirements for toll-quality voice because no ISP is involved.
Dedicated T1s are priced on a per-unit distance basis, making this a very cost-effective option over
short distances.
