POWER UP
No power up sequencing for the VDD inputs (1.8 V and 3.3 V) has to
be provided for the IDT82P2816. A Power-on reset will be initiated
during power up. Refer to Section 4.1 Reset.

HITLESS PROTECTION SWITCHING (HPS) SUM-
MARY
In today’s telecommunication systems, ensuring no traffic loss is
becoming increasingly important. To combat these problems, redun-
dancy protection must be built into the systems carrying this traffic.
There are many types of redundancy protection schemes, including 1+1
and 1:1 hardware protection without the use of external relays. Refer to
Figure-42, Figure-43 and Figure-44 for different protection schemes.
The IDT82P2816 provides an enhanced architecture to support both
protection schemes.
IDT82P2816 highlights for HPS support:
Independent programmable receive and transmit high impedance
for Tip and Ring inputs and outputs to support 1+1 and 1:1 redun-
dancy
Fully integrated receive termination, required to support 1:1 redun-
dancy
Enhanced internal architecture to guarantee High Impedance for
Tip and Ring Inputs and Outputs during Power Off or Power Fail-
ure
Asynchronous hardware control (OE, RIM) for fast global high
impedance of receiver and transmitter (hot switching between
working and backup board)

Rx:
Partially Internal Impedance Matching mode. A fixed external 120
resistor is placed on the backplane and provides a common termination for
T1/J1/E1 applications. The R_TERM[2:0] bits (b2~0, RCF0,...) setting is as follows: ‘000’ for T1 100
twisted pair cable, ‘001’ for J1 110 twisted
pair cable, ‘010’ for E1 120
twisted pair cable and ‘011’ for E1 75 coaxial cable.
