• 1 PP2S (Port Ref. In/Out): The clock reference constituted by a 1 PP2S signal (1
pulse every two seconds) transmitted through the RJ-48 REF IN/OUT port. For this
reason, this option is available only if a clock reference input has not been previ-
ously configured over the same port.
• 1 PPS (REF SMB): Generates a 1 PPS output synchronized (phase and frequency)
with the local oscillator through the SMB REF OUT port.
• 1 PP2S (REF SMB): The clock reference constituted by a 1 PP2S signal (1 pulse
every two seconds) transmitted through the SMB REF OUT port.

Parameter Description
Clock/PCM input Configures the Clock or PCM reference input interface:
• 2048 kHz (Port Ref. In/Out): The clock reference is
encoded as an unipolar, square wave 2048 kHz signal.
This signal is transmitted through the balanced RJ-48 Ref.
In / Out port.
• E1 (Port Ref. In/Out): The clock reference is encoded as
an ITU-T G.703 2048 kb/s signal with an all ones-payload.
This signal is transmitted through the balanced RJ-48 Ref.
In / Out port.
• 1544 kHz (Port Ref. In/Out): The clock reference is
encoded as an unipolar, square wave 2048 kHz signal.
This signal is transmitted through the balanced RJ-48 Ref.
In / Out port.
• T1 (Port Ref. In/Out): is encoded as an ITU-T G.703
1544 kb/s signal with an all ones-payload. This signal is
transmitted through the balanced RJ-48 Ref. In / Out port.
• 5 MHz (Port Ref. In/Out): This is a 5 MHz unipolar, square
wave 5 MHz clock transmitted through the RJ-48 Ref. In /
Out port.
• 10 MHz (Port Ref. In/Out): This is a 10 MHz unipolar,
square wave 10 MHz clock output transmitted through the
RJ-48 Ref. In / Out port.
Connector Configures the port connector in a Clock / PCM reference
input. Since all references of this type are currently transmit-
ted through the balanced RJ-48 Ref. In / Out port, connector
setting is not required.
