– Downstream – 2304 Kbps for single-pair; 4608 Kbps for 2-wire
– Upstream – 2304 Kbps for single-pair; 4608 Kbps for 2-wire
• Minimum transmission rate to sync
– 64 Kbps for MM702G2-W (2-Wire Mode) and 384 Kbps (4-Wire Mode)
• Connector
– RJ-11
• ATM (Asynchronous Transfer Mode)
– ATM Adaptation Layer - AAL5 (ITU I.363.5)—Supports encapsulation and de-encapsulation of AAL5
Protocol Data Units (PDUs) for convergence. Segmentation and Reassembly (SAR) layer segments and
reassembles AAL5 PDUs into ATM cells that are 48 byte SAR-PDUs.
• ATM Layer - Attaches or strips the 5-byte header to the 48-byte SAR-PDU.
– Cell Format - Complies with ITU I.361 ATM cell format. Cell delineation complies with ITU I.432 Cell
Delineation and HEC. Cells are fixed length (53 bytes), including 5 bytes of header and 48 bytes of
payload. Included in the header are the VPI and VCI number.
• Virtual Circuit type - Permanent Virtual Circuit (PVC) per ATM forum UNI Version 3.1.
– Maximum Virtual Circuits - 8 virtual circuits that can simultaneously connect to service providers for
sessions encapsulated either as PPP or RFC 1483 Bridging/Routing.
