Figure 6-234 Appearance of the 24-port E1/T1 DB100 to SMB port conversion box
The CR53CFE1 provides 24 E1/T1 interfaces. The connectors on the CR53CFE1 are of the
DB100 type, which cannot be directly used. Thus, you need to use transfer cables to connect
the 24 E1 port conversion box and the CR53CFE1. In this manner, the conversion box
provides RJ48 interfaces and SMB interfaces that can be directly used. The selection of the
balanced or unbalanced conversion box and associated E1/T1 cables is determined by site
survey results.

The remote interface is a 120-ohm balanced RJ48 interface.
− If the remote interface is a 120-ohm balanced RJ48 interface, you need to select
E1/T1 trunk cables with RJ48 connectors at both ends and a DB100 to RJ48 port
conversion box. The maximum transmission distance is 270 m ( 88.58 ft ).
The remote interface is a 75-ohm unbalanced SMB interface.
− If the remote interface is a 75-ohm unbalanced SMB interface, you need to select a
24-port E1/T1 DB100 to SMB port conversion box and suitable cables. In addition,
the cable end that is connected to the customer's device is not equipped with a
terminal, so the customer needs to prepare the terminal. In this case, the maximum
transmission distance is shorter than 200 m.
