Introduction to EI MultiVOIPs
(MVP3010 & MVP30-60)
We proudly present MultiTech’s E1 Digital Multi-VOIP products. The
MVP3010 is a rack-mount model and the MVP30-60 is an add-on
expansion card that doubles the capacity of the MVP3010 without
adding another chassis. All of these voice-over-IP products have fax
capabilities. All adhere to the European standard of E1 trunk telephony
using digital 30-channel time-division multiplexing, which allows 30
phone conversations to occur on the E1 line simultaneously. All can
also accommodate E1 lines of the ISDN Primary Rate Interface type
(ISDN-PRI).
Scale-ability. The MVP3010 is tailored to companies needing more
than a few voice-over-IP lines, but not needing carrier-class equipment.
When expansion is needed, the MVP3010 can be field-upgraded into a
dual E1 unit by installing the MVP30-60 kit, which is essentially a
second MultiVOIP motherboard that fits into an open expansion-card
slot in the MVP3010. The upgraded dual unit then accommodates two
E1 lines.
E1 VOIP Traffic. The MVP3010 accepts its outbound traffic from a E1
trunk that’s connected to either a PBX or to a telco/carrier. The
MVP3010 transforms the telephony signals into IP packets for
transmission on LANs, WANs, or the Internet. Inbound IP data traffic
is converted to telephony data and signaling.
When connected to PBX. When connected to a PBX, the MVP3010
creates a network node served by 10/100-Base T connections. Local
PBX phone extensions gain toll-free access to all phone stations directly
connected to the VOIP network. Phone extensions at any VOIP location
also gain local-rate access to the entire local public-switched telephone
network (PSTN) at every other VOIP location in the system.
When connected to PSTN. When the E1 line(s) connected to the
MVP3010 are connected directly to the PSTN, the unit becomes a Point-
of-Presence server dedicated to local calls off-net.
H. 323 & SIP. Being H.323 compatible, the MVP3010 can place calls to
telephone equipment at remote IP network locations that also contain
H.323 compatible voice-over-IP gateways. It will interface with H.323
software and H.323 gatekeeper units. H.323 specifications also bring to
voip telephony many special features common to conventional
telephony. H.323 features of this kind that have been implemented into
the MuliVOIP include Call Hold, Call Waiting, Call Identification, Call
Forwarding (from the H.450 standard), and Call Transfer (H.450.2 from
