• 1PPS—1PPS input for GPS Synchronization. This connector on the front panel can provide 1PPS output as well from Cisco ASR-920-12SZ router. The input or output direction can be configured using software. • 10MHZ—10MHz input for GPS Synchronization. This connector, present on the front panel, can also provide 1PPS output from the Cisco ASR-920-12SZ router.
A single USB 2.0 Type-A receptacle on the front panel of the router provides console access to ROMMON, Cisco IOS-XE, and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for connection to an external host computer. This interface requires the use of a Type-A to Type-A connector instead of a standard USB cable.
