Framer will read in the contents of this register, and insert it into the TR byte-field, within the very next out-
bound E3 frame.
The contents of this register, along with Tx TTB-1, and Tx TTB-3 through Tx TTB-15 are used to transmit 15
ASCII characters required for the E.164 numbering format.
3.3.2.49 Tx TTB-3 Register
This “Read/Write” byte-field, along with the “Tx TTB-0” through “Tx TTB-2” and “Tx TTB-4” through “Tx TTB-15” reg-
isters allows a user to define a “Trail Access Point Identifier” sequence of bytes, that will be transmitted to the
“Far-End” Terminal. The “Far-End” Receiving Terminal will use this sequence of bytes to verify that it is con-
nected to the proper “Transmitting Terminal”. The Transmit E3 Framer will take the contents of these 16 regis-
ters, and insert them into the TR byte of the outbound E3 frame. In the fourth of a set of 16 E3 Frames, the
Transmit E3 Framer will read in the contents of this register, and insert it into the TR byte-field, within the very
next outbound E3 frame.
The contents of this register, along with Tx TTB-1, Tx TTB-2 and Tx TTB-4 through Tx TTB-15 are used to
transmit 15 ASCII characters required for the E.164 numbering format.
3.3.2.50 Tx TTB-4 Register
This “Read/Write” byte-field, along with the “Tx TTB-0 through Tx TTB-3” and “Tx TTB-5” through “Tx TTB-15” reg-
isters allows a user to define a “Trail Access Point Identifier” sequence of bytes, that will be transmitted to the
“Far-End” Terminal. The “Far-End” Receiving Terminal will use this sequence of bytes to verify that it is con-
nected to the proper “Transmitting Terminal”. The Transmit E3 Framer will take the contents of these 16 regis-
ters, and insert them into the TR byte of the outbound E3 frame. In the fifth of a set of 16 E3 Frames, the
Transmit E3 Framer will read in the contents of this register, and insert it into the TR byte-field, within the very
next outbound E3 frame.
The contents of this register, along with Tx TTB-1 through Tx TTB-3 and Tx TTB-5 through Tx TTB-15 are used
to transmit 15 ASCII characters required for the E.164 numbering format.
