SATURN QUAD USER NETWORK INTERFACE FOR J2, E3, T3
1
FEATURES
Single chip quad ATM User Network Interface operating at 44.736 Mbit/s,
34.368 Mbit/s, and 6.312 Mbit/s conforming to ATMF-95-1207R1, ATMF-94-
0406R5, and AF-PHY-0029.000. Each line can be individually configured for
the desired rate.
•
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 TA-TSY-000773, TA-TSY-000772, and E1
and E3 transmission systems according to the ETSI 300-269 and ETSI 300-
270.
