48 T1 Interface
Switch S3-6: Annex. Annex A and B offer spectral compatibility with T1 and E1 signals respectively, this fea-
ture reduces the interference between DSL lines and adjacent E1or T1 lines. For regions where T1 is used,
select Annex A.
Switch S3-7. Use S3-7 to configure the TDM interface for T1 or E1 service. Note that selecting E1 automati-
cally sets the E1 line rate to HDB3, line impedance to 120-Ohms. Selecting T1 automatically sets the framing
to Extended Super Frame and B8ZS line code.
Switch S3-8. Switch S3 applies to E1 applications, for T1 applications this switch is ignored.
Web Interface Configuration
The T1 interface page is accesed from the Main Menu > E1/T1. This page allows configuration of T1
paraemeters as follows:
Time Slot Select. For a T1 using all 24 time slots, enter 1-24, for fractional T1 enter in any format for exam-
ple: 1,2,3,5; or 1-5,10-24. Any entry for timeslots above 24 will return and invalid selection message.
