AT&T Collaborate quick reference EdgeMarc 250 Integrated Access Device

The EdgeMarc 250® integrated access device converts multiple types of input signals (analog phone, digital phone, and fax) into a common communications format.

The EdgeMarc 250 provides Voice over IP (VoIP) and fax over IP for use with the AT&T CollaborateSM service.

Collaborate is a VoIP system that transports calls over the AT&T IP network rather than over the traditional public switched telephone network.


Use the EdgeMarc 250 to connect analog devices. The EdgeMarc 250 comes with 4 analog foreign exchange subscriber (FXS) ports that support voice, fax, and other data devices such as alarm systems and point of sale (POS) terminals. This device has a local area network (LAN) switch (non-power over ethernet) that you can use to connect up to 7 IP phones. Use one LAN port to connect the EdgeMarc 250 to your LAN.
