Cisco 7600 Series Routers (on 7600-SIP-400)
Cisco ASR 1000 Series Router (IEEE 1588-2008 not supported)
Port density per SPA
2 Gigabit Ethernet ports (usable in combination of Small Form-Factor Pluggable [SFP] ports for a total of 2 Gigabit
Ethernet ports)
Ethernet ports)
Physical interfaces
●
Built-in RJ-45
●
Clock interfaces
◦
Four DIN 1.0/2.3 interfaces
◦
One mini-BNC interface
●
Two SFP Interfaces for Gigabit Ethernet and Synchronous Transport Module/Optical Carrier (STM/OC) SFPs
The above interfaces support:
●
External timing interface (BITS) in/out (1944 kbps, 2048 kbps, 2048 kHz)
●
GPS 1PPS/10 MHz In/Out
●
GPS ToD (NTP format) in/out (on built-in RJ-45)
ToD and 1 PPS OUT when SPA is configured in PTP slave mode.
LED indicators
SPA status: Bicolored green and amber LEDs encode the SPA status as follows:
●
LED Off: SPA is powered off.
●
LED Green: SPA is powered on and operational.
●
LED Amber: SPA is powered on and initializing (or being configured).
In addition to the status LED, the SPAs also have a bicolored, surface-mounted, right-angled LED dedicated to
each port to indicate port status. The green and amber LEDs encode the port status as follows:
each port to indicate port status. The green and amber LEDs encode the port status as follows:
●
LED Off: Port is not enabled by software.
●
LED Green: Port is enabled by software, and there is a valid Ethernet link.
●
LED Amber: Port is enabled by software, but there is a problem with the Ethernet link.
The Rx Synchronization Port LEDs encode the port status as follows:
●
LED Off: Port is not enabled by software.
●
LED Green: Port is enabled by software, and there is a valid synchronization signal coming in with an expected
frequency.
●
LED Amber: Port is enabled by software and there is a problem with the synchronization signal, such as:
◦
Loss of signal (LoS)
◦
Loss of framing (LoF) for T1/E1 lines
◦
Wrong incoming frequency
The Tx Synchronization Port LEDs, encode the port status as follows:
●
LED Off: Port is not enabled by software.
●
LED Green: Port is enabled by software, and the source of the line is in a good state.
●
LED Amber: Port is enabled by software, but the source of the line is not available, and the output runs in
holdover mode.
