Introduction to TI MultiVOIPs (MVP2410 & 
MVP24-48) 
We proudly present MultiTech’s T1 Digital Multi-VOIP products.    
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.  These voice-over-IP products have fax 
capabilities.  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.  They can also accommodate T1 lines of the ISDN 
Primary Rate Interface type (ISDN-PRI).

Scale-ability.  The MVP2410 is 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 MVP2410 accepts its outbound traffic from a T1 
trunk that’s connected to either a PBX or to a telco/carrier.  The 
MVP2410 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 MVP2410 
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 
MVP2410 are connected directly to the PSTN, the unit becomes a Point-
of-Presence server dedicated to local calls off-net.
