XRT7250

DS3/E3 FRAMER IC

áç

REV. 1.1.1

(e.g., the first byte within the 16 byte Trail Trace Buffer

Message). The remaining bits: C0 - C6 contain the

CRC-7 value that was calculated over the previous 16

byte Trail Trace Buffer Message.

NOTES:

1. The XRT7250 Framer device will not compute or

verify this CRC-7 value. It is up to the user's hard-

ware and/or software to compute and verify this

value.

2. For more information on the use of this register,

please see Section 5.3.2.9.

2.3.3.12 Receive E3 TTB-1 Register (E3, ITU-T

G.832)

This Read-Only register contains the second (2nd)

byte within the 16 byte Trail Trace Buffer Message,

that has been received from the Far-End Terminal.

This register typical contains an ASCII character that

is required for the E.164 numbering format.

NOTE: For more information on the use of this register,

please see Section 5.3.2.9.

2.3.3.13 Receive E3 TTB-2 Register (E3, ITU-T

G.832)

This Read-Only register contains the third (3rd) byte

within the 16 byte Trail Trace Buffer Message, that

has been received from the Far-End Terminal. This

quired for the E.164 numbering format.

NOTE: For more information on the use of this register,

please see Section 5.3.2.9.

2.3.3.14 Receive E3 TTB-3 Register (E3, ITU-T

G.832)

This Read-Only register contains the fourth (4th) byte

within the 16 byte Trail Trace Buffer Message, that

has been received from the Far-End Terminal. This

quired for the E.164 numbering format.

NOTE: For more information on the use of this register,

please see Section 5.3.2.9.
