DescriptionThe RL56CSM provides the processing core for three channels of a central site Remote Access Server supporting high speed T1/E1/PRI digital lines. The OEM adds two oscillators, SDRAM, and discrete components to complete the Multi-Service Access Processor system.
The access processor RL56CSM includes a full-featured, self-contained data/fax/Voice modem solution shown in Figure 1-1. Data
modem handshake, fax modem protocol, voice codecs, and ISDN data connection functions are supported and controlled through the AT command set.
