FOUR CHANNEL COMBINED E1/T1/J1

TRANSCEIVER / FRAMER

Pin Name

MVBRD /

Type Pin No. Function

Output L4

H-MVIP Backplane Receive Data (MVBRD). MVBRD carries the recovered

T1 or E1 channels that have passed through the elastic store. Each MVBRD

signal carries the channels of four complete T1’s or E1’s. MVBRD carries the

T1 or E1 data equivalent to BRPCM[1:4].

MVBRD is aligned to the common H-MVIP 16.384 MHz clock, CMV8MCLK,

frame pulse clock, CMVFPC, and frame pulse, CMVFPB. MVBRD is updated

on every second rising edge of the common H-MVIP 16.384 MHz clock,

CMV8MCLK, as fixed by the common H-MVIP frame pulse clock, CMVFPC.

CCSBRD

CASBRD / Output E1

BRPCM[1]

Common Channel Signaling Backplane Receive Data (CCSBRD). In T1

mode, CCSBRD carries the Common Channel Signaling (CCS) channels

extracted from each of the 4 T1’s. In E1 mode, CCSBRD carries up to 3

timeslots (15,16, 31) from each of the 4 E1’s. CCSBRD is formatted

according to the H-MVIP standard.

CCSBRD is aligned to the common H-MVIP 16.384 MHz clock, CMV8MCLK,

the 4.096 MHz frame pulse clock, CMVFPC, and frame pulse, CMVFPB.

CCSBRD is updated on every second rising edge of CMV8MCLK as fixed by

the common H-MVIP frame pulse clock, CMVFPC.

CCSBRD shares the same pin as MVBRD. In Receive Clock Slave: H-MVIP

mode, this output is MVBRD. In Receive Clock Slave: Full T1/E1 mode,

CCSBRD can be optionally enabled. In all other modes, this output is unused

and driven low.

Channel Associated Signaling Backplane Receive Data (CASBRD).

CASBRD carries the Channel Associated Signaling (CAS) stream extracted

from all the T1 or E1 channels. CASBRD carries CAS for four complete T1’s

or E1’s. CASBRD carries the T1 or E1 signaling equivalent to BRSIG[1:4].

CASBRD carries the corresponding CAS values of the channel carried in

MVBRD.

CASBRD is aligned to the common H-MVIP 16.384 MHz clock, CMV8MCLK,

the 4.096 MHz frame pulse clock, CMVFPC, and frame pulse, CMVFPB.

CASBRD is updated on every second rising edge of CMV8MCLK as fixed by

the common H-MVIP frame pulse clock, CMVFPC.

CASBRD shares the same pin as BRPCM[1]. In Receive Clock Slave: H-

MVIP mode, this output is CASBRD. In all other modes, this output is

BRPCM[1]. By default this output is BRPCM[1].
