Digital and Analog Voice Interworking Overview
VComp bundles solve
the following interoperability requirements:
- Interoperability between digital and analog voice channels.
For example, when remote sites use analog trunks and the central site
voice switch location uses digital T1/E1 connections. In this case,
you can use VComp bundles to aggregate the analog sites into higher-density
digital interfaces on the central voice switch.
- Interoperability between sites inside and outside the
United States. Generally, mu-law companding is used inside the United
States and a-law companding is used in Europe and elsewhere. You can
use mu-law to a-law conversion between E1 and T1 voice interfaces
to connect these sites.
