When testing E1 circuits, either BNC or RJ48 connectors can
be used.
E1 (BNC)
specifications
Table 13 on page 109 through Table 16 on page 110 list
specifications for the E1 (BNC) connectors.
Frequency Range: 1.544 MHz ±250 ppm
Accuracy: ± 1.5 ppm, ± 1 ppm per year aging
Resolution: 1 Hz or 1 ppm
Level dBdsx
1
Range: +2.5 dBdsx to -37 dBdsx
Resolution: 0.1 dB
Level dBm
2
Range: +19.0 dBm to -10.5 dBm
Resolution: 0.1 dB
1. The designation dBdsx is a level measurement in dB relative to dsx level, which is 6 V peak-
peak. A signal with a peak-peak level of 6V corresponds to 0 dBdsx.
2. Available only when unframed all ones (AIS) signal is detected.

NOTE:
The E1 and DS1 interfaces should not be connected at the
same time. Multiple connections can influence the integrity
of the signal under test. After running your test, disconnect
from one interface before connecting to the other interface.
