Description

Loop Telecomís T1/E1 ATM Frame Relay is a plug-in card, designed for the Loop-AM3440 Muxmaster Series.
When used within the 3440, this card combines the functions of ATM/Frame Relay and CSU/DSU. With this card,
access from a Frame Relay customerís FRAD equipment to an ATM/ FR switch is accomplished within one box,
resulting in savings in cost and space.
