Section 6
TDM Interface
The MPC8560 contains two Serial Interface (SI) blocks (SI1 and SI2) programmed to handle
eight Time-Division Multiplexed (TDM) lines. Each SI connects to four independent TDM
channels (either T1/J1 or E1) and the Time-Slot Assignment (TSA).
The TSA is capable of combining data from any of the SCCs and FCCs onto eight TDMs. The
TDM processes channelized serial data such as T1, E1 or J1. The TDM interface consists of:
• Three signals for the transmitter (TDMx TXD, TDMx TCLK, TDMx TSYNC)
• Three for the receiver (TDMx RXD, TDMx RCLK, TDMx RSYNC)
TDM FRAMER AND LINE INTERFACE
The Pm8560 module includes support for eight links using one IDT82P2288 octal T1/E1/J1
(long haul/short haul) framer and line interface (LIU).
Framer
• Each link can be configured as T1, E1, or J1
• Frame alignment/generation for T1 (per ITU-T G.704, TA-TSY-000278, TR-TSY-000008),
E1 (per ITU-T G.704), J1 (per JT G.704) and unframed mode
• Signaling extraction/insertion for CAS and RBS signaling
• Each link has three HDLC controllers with separate 128-byte transmit and receive FIFOs
per controller
• Supports Signaling System #7 (SS7)
Line Interface
• Supports T1/E1/ J1 long haul/short haul line interface
• Selectable internal line termination impedance: 100 ohm (T1), 75/120 ohm (E1), and
110 ohm (J1)
• Supports G.722 non-intrusive monitoring and T1.102 line monitor
• Separate power down function per each receiver and transmitter
