Introduction to TI MultiVOIPs (MVP2400,
MVP2410, & MVP24-48)
We proudly present MultiTech’s T1 Digital Multi-VOIP products.
The MVP2400 is a tabletop model; the MVP2410 is a rack-mount model; and
the MVP24-48 is an add-on expansion card that doubles the capacity of the
MVP2410 without adding another chassis. All of these voice-over-IP products
have fax capabilities. All of these models adhere to the North American
standard of T1 trunk telephony using digital 24-channel time-division
multiplexing, which allows 24 phone conversations to occur on the T1 line
simultaneously. All can also accommodate T1 lines of the ISDN Primary Rate
Interface type (ISDN-PRI).
Scale-ability. The MVP2400 and MVP2410 are tailored to companies needing
more than a few voice-over-IP lines, but not needing carrier-class equipment.
When expansion is needed, the MVP2410 can be field-upgraded into a dual T1
unit by installing the MVP24-48 kit, which is essentially a second MultiVOIP
motherboard that fits in an open expansion-card slot in the MVP2410. The
upgraded dual unit then accommodates two T1 lines.
T1 VOIP Traffic. The MVP-2400/2410 accepts its outbound traffic from a T1
trunk that’s connected to either a PBX or to a telco/carrier. The MVP-
2400/2410 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 MVP-2400/2410
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 toll-
free access to the entire local public-switched telephone network (PSTN) at
every other VOIP location in the system.
When connected to PSTN. When the T1 line(s) connected to the MVP-
2400/2410 are connected directly to the PSTN, the unit becomes a Point-of-
Presence server dedicated to local calls off-net.
