HIGH DENSITY T1/E1 FRAMER

AND M13 MULTIPLEXER

PROPRIETARY AND CONFIDENTIAL

Pin Name

Type

No.

Function

the RSCLKR bit in the DS3 Master Unchannelized

Interface Options register. By default RDATO will be

updated on the falling edge of RGAPCLK or RSCLK.

This signal shares a signal pin with ID[1] and MVID[1].

This signal will be RDATO only when enabled for

unchannelized DS3 operation.

RFPO/RMFPO

Output AB5 Framer Receive Frame Pulse/Multi-frame Pulse

(RFPO/RMFPO). RFPO/RMFPO is valid when the

TECT3 is configured to be in framer only mode by

setting the OPMODE[1:0] bits in the Global

Configuration register.

RFPO is aligned to RDATO and indicates the position

of the first bit in each DS3 M-subframe.

RMFPO is aligned to RDATO and indicates the

position of the first bit in each DS3 M-frame. This is

selected by setting the RXMFPO bit in the Master

Framer Configuration Registers.

RFPO/RMFPO is updated on either the falling or rising

edge of RSCLK depending on the setting of the

RSCLKR bit in the DS3 Master Unchannelized

Interface Options register.

This signal shares a signal pin with IFP[1]. When

enabled for unchannelized DS3 operation this signal

will be RFPO/RMFPO, otherwise it will be IFP[1].

ROVRHD

Output Y6

Framer Receive Overhead (ROVRHD). ROVRHD is

valid when the TECT3 is configured as a DS3 framer

by setting the OPMODE[1:0] bits in the Global

Configuration register.

ROVRHD will be high whenever the data on RDATO

corresponds to an overhead bit position. ROVRHD is

updated on the either the falling or rising edge of

RSCLK depending on the setting of the RSCLKR bit in

the DS3 Master Unchannelized Interface Options

This signal shares a signal pin with ID[2] and

CASID[1]. This signal will be ROVRHD only when

enabled for unchannelized DS3 operation.
