The ACS-ATM card consists of a main board and sub-module card. The main board is a
variation of the existing Advanced Communication Server (ACS). The sub-module card
handles all ATM functionality’s, including the Physical Layer, ATM Layer, and Adaptation
Layer. ATM connectivity is provided to and from the following system cards:
• WAN (all card types)
• HSU (all card types)
• FXS, FXO, FXS-C, FXO-C
• E&M (all card types)
• BRI (U*8 and SC cards only)
• FRAD 232*10
Incoming traffic is directed through the internal bus system to the ACS-ATM card, which
provides adaptation and encapsulation. The ATM output in the first release of the product is
an electrical DS3. Typically, the ATM connection is a local ATM switch which multiplexes
virtual circuits originating from the IMACS with other high-speed traffic. The ACS-ATM card
is capable of handling both Variable Bit Rate and Constant Bit Rate Applications.
