Rate per port

10/100/1000Base-T (Gigabit) Ethernet

10/100Base-T Ethernet 10/100Base-T full duplex
Number of multicast addresses supported 64K 4K Unlimited. Fixed multicast switching rules
Switching capacity Up to 20 M packets/second Up to 1.79 M packets/second Up to 1.07 M packets/second
Management Managed switch which allows for :
- bandwidth control
- Simple Network Management Protocol (SNMP)
- static multicast routing
Unmanaged switch module compatible with any TTC miniature data acquisition unit.
Maximum data bandwidth aggregation Up to 8 Gbps Up to 500 Mbps Up to 100 Mbps. Data is aggregated in one direction only.
IEEE 1588 timing model Boundary clock Boundary clock End-to-end transparent clock
Internal PTP grandmaster-capable Yes Yes No
PTP grandmaster time source - IRIG-B time (AC or DC)
- GPS time with included GPS receiver and an attached GPS antenna
- Internal real-time PTP clock with built-in ten-year battery backup.
N/A
Time generator Generates IRIG-B (AC and DC) time that is synchronized to the internal PTP clock. N/A
Internal clock drift 2 PPM over temperature, free-running during loss of master clock.


3.5 PPM over temperature for the battery-backed-up real-time clock in its powered-off state.
N/A
Additional ports 1 PPS output signal and RS-232/422 None
