E1-DOOR Encryption Gateway for E1/FE1 over IP

The E1-DOOR provides circuit encryption of E1 circuits either over E1 networks or over IP network with encapsulated form. They are popular in military, police and banking environments.

CXR offers the encryption methodology AES 256bits encryption (Advanced Encryption Standard) which is a FIPS approved symmetric encryption algorithm.

The E1-DOOR-xx encrypts the n TS (from 1 to 31) of the E1 G.704 and forwards it to the G.704 E1 or to the encapsulated function of CESoIP.

The E1-DOOR-E1+E1 provides an automatic backup for an E1 circuit with a second E1 circuit (1+1 protection) with encryption of both paths.

The E1-DOOR-E1+IP provides an automatic backup for 1 E1 circuit via an E1 over IP IP with encryption of both paths.

The management of the encryption key is done automatically by the E1-DOOR. The master automatically changes the key once a minute on an annual basis.
