The 8-port fractional T1 interface module allows only one bundle. The time slots can only be
bundled into one n × 64 Kbps/56 Kbps channel, where the value range of n is 1 to 31. The
module does not support the PRI mode.
• HMIM-8E1T1(-F) jumper settings
You can set an interface to a 75-ohm E1 interface, 100-ohm T1 interface, or 120-ohm E1
interface at the CLI or by using the jumper connection method. By default, an interface is a
75-ohm E1 interface.
 For a 75-ohm E1 interface, the jumper is connected to pins 1 and 2, pins 7 and 8, and pins
11 and 12.
 For a 100-ohm T1 or 120-ohm E1 interface, the jumper is connected to pins 1 to 3, pins 5 to
7, pins 9 and 10, and pins 11 to 13.
Figure 105 Jumper settings
NOTE:
•
An interface corresponds to a jumper connector. Pin settings for the jumper connectors are
the
same.
•
Each interface comes with four jumper caps.
• All interfaces must operate in the same mode simultaneously.
