11.1.3 Interfaces
Interface types
There are six interfaces on the iTN2100-TSU panel, as listed in Table 11-1.

Description
2048 KHz or 2048
Kbit/s
(1–2)
RJ45

Supports two 2048 Kbit/s or 2048 KHz external
synchronization interfaces (120Ω balanced
interfaces).

Support protection, electrical level change, and
impedance matching of external clock signals.

Support SSM signal processing and clock
recovery of 2 Mbit/s signals.

Support 2 MHz and 2 Mbit/s signal templates
that meet the G.703 requirements.
1PPS+TOD(I/O)
(1–2)
RJ45

Support two 1PPS+TOD interfaces for
configuring time signal input and output.

One 1PPS+TOD electrical level support RS422
only and the other 1PPS+TOD electrical level
supports RS422 and RS232.

When 1PPS+TOD electrical level is set to
RS232, it needs to cooperate with the APPS
interface. It means that the 1PPS+TOD
interface transmits TOD information only and
supports translating different forms of TOD.
1PPS(I/O)
BNC

Support one 1PPS interface for configuring
time signal input and output.

Support translating different forms of TOD.

Support TTL electrical level.
