PM7347 General Description

The PM7346 S/UNI-JET is an ATM physical layer processor with integrated DS3, E3, and J2 framers. It supports PLCP sublayer DS1, DS3, E1, and E3 processing and ATM cell delineation. The S/UNI-JET contains:
• An Integral DS3 framer that provides DS3 framing and error accumulation in accordance with ANSI T1.107, and T1.107a.
• An Integral E3 framer that provide E3 framing in accordance with ITU-T Recommendations G.832 and G.751.
• An Integral J2 framer that provide J2 framing in accordance with ITU-T Recommendation G.704 and I.432. When configured for various transmission system sublayer processing, the S/UNI-JET accepts and outputs the appropriate type of bipolar and unipolar signals as described in Table 2:

PM7347 Features

The S/UNI®-JET is a single chip Asynchronous Transfer Mode (ATM) User Network Interface (UNI) operating at 44.736 Mbit/s, 34.368 Mbit/s, and 6.312 Mbit/s that:
• Conforms to AF-Physical (PHY)-0054.000, AF-PHY-0034.000 and AF-PHY-0029.000.
• Implements ATM Direct Cell Mapping into DS1, DS3, E1, E3, and J2 transmission systems according to ITU-T Recommendation G.804.
• Provides a UTOPIA Level 2 compatible ATM-PHY Interface.
• Implements the Physical Layer Convergence Protocol (PLCP) for DS1 and DS3 transmission systems according to the ATM Forum User Network Interface Specification and ANSI TATSY- 000773, TA-TSY-000772, and E1 and E3 transmission systems according to the ETSI 300-269 and ETSI 300-270.
• Supports Switched Multi-megabit Data Service (SMDS) and ATM mappings into various rate transmission systems as shown in Table 1:
