1.1 Introduction
The Advanced CMOS Frame Aligner PEB 2035 (ACFA) is a monolithic CMOS device which
implements the interface to primary rate PCM carriers. It may be programmed to operate in 24-
channel (T1) and 32-channel (CEPT) carrier systems.
The ACFA features include: selectable multiframe (six multiframe formats), error checking (CRC4,
CRC6), multiple line codes (HDB3, B8ZS, AMI), and programmable signaling paths. The device
includes functions which meet newest CCITT (Blue Book) and FTZ recommendations for primary
rate interfaces and the AT&T Digital Multiplexed Interface specifications (DMI) plus some additional
features requested by the market. Controlling and monitoring of the device is performed via a
parallel eight-bit microprocessor bus.
The circuit contains a two-frame elastic memory which ensures wander absorption between the
PCM carrier and a synchronous, system internal highway.
All signaling types - CCS, CAS and bit-robbed signaling in conjunction with Clear Channel
Capability - are supported by the ACFA. In addition, the ACFA allows flexible access to facility data
link and service channels. Extensive testing capabilities are included.
The ACFA is suitable for a wide range of voice and data applications. Below you find a list of
equipment as described by the CCITT which potential ACFA applications.

Function
Receive Channel Parity
Even/odd parity signal which supplements the
number of ones of a received channel to an even/
odd quantity while sending channel data to output
RDO. The parity type is programmed by bit
RC0.RPYS.
7 5 RFSPQ O
PCM 24: Additional Function Receive
If enabled via bit ACR.DLC, this output provides a
4-kHz signal which marks the DL-bit position
within the data stream on RDO. It can be used as
receive strobe signal for external data link
controllers.
Receive Frame Synchronous Pulse (active low)
Framing pulse derived from the received PCM
route signal. During loss of synchronization (bit
RSR.LOS), this pulse is suppressed (not
influenced during alarm simulation).
Pulse frequency: 8 kHz
Pulse width:
488 ns [PCM 30]
648 ns [PCM 24]
