Datasheet

Important:
The switch displays the interface speed of the T1/E1 SFP as a 100 Mb/s connection even
though the interface is operating at the appropriate WAN speed. The system uses this value
for STP path cost and MLT utilization.
Important:
Avaya recommends that you enable egress traffic shaping on the port to 1.544 Mbps when
using the T1 SFP to guarantee appropriate Quality of Service and traffic prioritization.
The following table describes the T1 SFP specifications.

The T1 SFP uses an RJ-48C connector (see the following figure), which is similar to an RJ-45
connection, but with different pinouts.
The following table describes the RJ-48C pinouts.
