PEB20591 Features
VIP is a universal ISDN transceiver IC for differentinterface modes (S/T or UPN).
• Eight 2B+D line interfaces with full duplex transceivers
S/T interfaces at 192 kbit/s with line transceivers according to ITU-T I.430, ETSI 300.012 and ANSI T1.605
UPN interfaces at 384 kbit/s with line transceivers according to ZVEI standard
Receive timing recovery
Conversion between pseudo-ternary and binary codes
Conversion between UPN or S/T frames and IOM-2000 frame structures
Execution of test loops
Frame alignment in trunk applications with maximum wander correction of ± 25 µs
UPN interface compatible to OCTAT-P (PEB 2096)1)
S/T interface compatible to QUAT-S (PEB 2084)2)
• IOM-2000 interface to DELIC supporting up to three VIPs (24 channels)
Transceiver initialization and configuration
Control of layer-1 activation/deactivation
Exchange of command and status information
• Signaling control for all VIP channels by dedicated HDLC controllers in DELIC
• Single 3.3 V power supply
• JTAG IEEE1149.1-compliant test interface with dedicated reset input
Note: UPN refers to a version of the UP0 interface (meeting the ZVEI standard) with a
reduced loop length of up to 1.3 km, depending on the type of cable.
