PM73124

Preliminary PM73124 www.DataSheet4U.com AAL1gator™-4 4 Link CES/DBCES AAL1 SAR FEATURES Supports four structured/unstructured T1 or E1 links, or one unstructured DS3, E3 or STS-1/STM-0 link over an AAL1 CBR ATM network. Compliant with ATM Forum's CES (AFVTOA-0078), and ITU-T I.363.1. Supports up to 128 VCs. Supports n x 64 (consecutive channels) and m x 64 (nonconsecutive channels) structured data format with channel associated signaling (CAS) support. Internal E1/T1 clock synthesizers provided for each line which can be controlled via internal synchronous residual time stamp (SRTS) or an internal programmable weighted moving average adaptive clocking algorithm in unstructured mode. Clock synthesizers can also be controlled externally to provide customization of SRTS or adaptive clocking methods. Provides transparent transmission of CCS and CAS and termination of CAS signaling. Compliant with ATM Forum's Dynamic Bandwidth Circuit Emulation Service (DBCES) AF-VTOA-0085. Supports idle channel detection via processor intervention, CAS signaling, or data pattern detection. Provides idle channel indication on a per channel basis. Supports AAL0 mode, selectable on a per VC basis. Provides transmit and receive buffers which can be used for OAM cells as well as any other user-generated cells such as AAL5 cells for ATM signaling. Provides an optional 8/16-bit AnyPHY™ slave interface. Provides a three cell FIFO for UTOPIA loopback support on a per VC basis or a ...
