2. P2, P4, P6, P8: E1 /10MHz / 2.048MHz unbalanced Receivers
These unbalanced Receiver ports accept an unbalanced E1/2.048MHz (75 ohm) or 10MHz (50
ohm) signal for Wander measurement. Single-ended BNC connector.
3. P9, P10, P11, P12: 1pps unbalanced Receivers
These unbalanced Receiver ports accept an unbalanced 1pps signal for 1pps Accuracy
measurements or 1pps wander measurements. Single-ended 50ohm BNC connector.
4. Display
During the power up process, the display shows the following information:
‘Graphics in any Direction’ (manufacturer’s logo) then,
‘Status: init …’ (Paragon-t embedded software version shown e.g. E.10.24 19/08/11) then,
‘Status: idle’ (Paragon-t hardware IP address shown).
The unit is now ready for operation.
During operation, the status message reflects the operating condition of the Paragon-t.
5. P14, P17, P20, P34: E1 / T1 balanced Receivers
These balanced Receiver ports accept a balanced E1/2.048MHz (120ohm) or T1 (100ohm) signal
for Wander measurement. Balanced RJ48 connector.
As per the copy of the Paragon-t’s Rear Panel silkscreen label above, the E1 or T1 balanced signal
should be applied on the ports’ receiver (Rx) pins i.e. pins 1 and 2. Pin 3 is GND.
The ports’ Transmitter (Tx) pins i.e. pins 4 and 5 are currently not enabled in this release but may
be at some future release.
6. P13, P16, P19, P22: 1GbE SFP (optical) Ports
For connection to an optical Ethernet device for SyncE wander measurements. The ports are
intended to accept optical 1GbE SFPs (customer supplied).
7. P15, P18, P21, P24: 100BT, 1000BT (electrical) ports
For connection to an electrical Ethernet device for SyncE wander measurements. The ports are
intended to accept an RJ 45 100BT or 1000BT electrical Ethernet cable.
8. P25, P26, P27, P28: 1pps balanced Rx + ToD
These balanced Receiver ports accept a balanced 1pps signal for 1pps Accuracy measurements or
1pps Wander measurements. The ports also accept a ToD (Time of Day) serial string for ToD
display purposes. Balanced 120ohm, RJ48 connector.
