DS2154 Dallas Semiconducotr, DS2154 Datasheet - Page 55

• Manufacturer Part Number: DS2154
• Description: Enhanced E1 Single Chip Transceiver
• Manufacturer: Dallas Semiconducotr

RCBR1/RCBR2/RCBR3/RCBR4:
RECEIVE CHANNEL BLOCKING REGISTERS (Address=2B to 2E Hex)
TCBR1/TCBR2/TCBR3/TCBR4:
TRANSMIT CHANNEL BLOCKING REGISTERS (Address=22 to 25 Hex)
NOTE:
If CCR3.6=1, then a 0 in the TCBRs implies that signaling data is to be sourced from TSER (or TSIG if
CCR3.2=1) and a 1 implies that signaling data for that channel is to be sourced from the Transmit
Signaling (TS) registers. See definition below.
TCBR1/TCBR2/TCBR3/TCBR4: DEFINITION WHEN CCR3.6=1
*=CH1 and CH17 should be set to 1 to allow the internal TS1 register to create the CAS Multiframe
Alignment Word and Spare/Remote Alarm bits.
