T1 Versus E1 Telephony Environments

We present separate chapters for the MVP2410 MultiVOIP (this chapter) and the MVP3010 MultiVOIP (Chapter 7) because the respective telephony environments in which they operate have different standards and conventions. The MVP2410 is designed to operate under North American or T1 standards; the MVP3010 is designed to operate under European or E1 standards. The configuration of the phonebook is the same in either case. However, differences in the telephony environment give rise to different examples in each case. Series II analog MultiVOIP units (MVP130, MVP130FXS, MVP210, MVP410, and MVP810) can be operated in either the T1 or E1 environments. The examples in this chapter show these analog voip units being used in the same system as the MVP2410 digital MultiVOIP.

MultiVOIP Phonebooks

When a VoIP serves a PBX system, it’s important that the operation of the VoIP be transparent to the telephone end user. That is, the VoIP should not entail the dialing of extra digits to reach users elsewhere on the network that the VoIP serves. On the contrary, VOIP service more commonly reduces dialed digits by allowing users (served by PBXs in facilities in distant cities) to dial their co-workers with 3-, 4-, or 5-digit extensions as if they were in the same facility.

Furthermore, the setup of the VoIP generally should allow users to make calls on a non-toll basis to any numbers accessible without toll by users at all other locations on the VoIP system. Consider, for example, a company with VOIP-equipped offices in New York, Miami, and Los Angeles, each served by its own PBX. When the VOIP phone books are set correctly, personnel in the Miami office should be able to make calls without toll not only to the company’s offices in New York and Los Angeles, but also to any number that’s local in those two cities.

To achieve transparency of the VoIP telephony system and to give full access to all types of non-toll calls made possible by the VOIP system, the VoIP administrator must properly configure the “Outbound” and “Inbound” phone-books of each VoIP in the system.

The “Outbound” phonebook for a particular VoIP unit describes the dialing sequences required for a call to originate locally (typically in a PBX in a particular facility) and reach any of its possible destinations at
