DUAL T1/E1/J1 FRAMER/LIU COMBO - E1 REGISTER DESCRIPTION

REV. V1.2.0

TxIMODE[1]

R/W

Transmit Interface Mode selection

This bit determines the transmit interface speed. The exact function of

these two bits depends on whether Multiplexed mode is enabled or dis-

abled. Table 28 and Table 29shows the functions of these bits for non-

multiplexed and multiplexed modes.:

TRANSMIT INTERFACE SPEED

2.048Mbit/s. (Base Rate)

Transmit Backplane interface signals include:

TxSERCLK is an input or output clock at

2.048MHz

TxMSYNC is the superframe boundary at 2ms

TxSYNC is the single frame boundary at 125 us

TxSER is the base-rate data input

2.048Mbit/ (High-speed MVIP Mode)

Transmit Backplane interface signals include:

TxSERCLK is an input clock at 2.048MHz

TxMSYNC will become the high speed input clock

at 2.048MHz to input high-speed data

TxSYNC indicates the single frame boundary

TxSER is the high-speed data input

4.096Mbit/s High-speed mode:

Transmit Backplane interface signals include:

TxSERCLK is an input clock at 2.048MHz

TxMSYNC will become the high speed input clock

at 4.096MHz to input high-speed data

TxSYNC indicates the single frame boundary

TxSER is the high-speed data input

8.192Mbit/s High-speed mode:

Transmit Backplane interface signals include:

TxSERCLK is an input clock at 2.048MHz

TxMSYNC will become the high speed input clock

at 8.192MHz to input high-speed data

TxSYNC indicates the single frame boundary

TxSER is the high-speed data input
