The D’Cryptor  PE is also integrated into other D’Crypt products such as the PSTN and mini-M phone encryptor as well as the E1 Link Encryptor.
D’Crypt’s E1 Link Encryptor provides end-to-end protection on a 2.048 Mbit/s data link. The encryptor intercepts data in a protocol-independent manner and does not introduce any overheads due to synchronization. The encryptor also has the ability to check and detect the data link for integrity and quality. It re-synchronizes in the face of channel errors or erasures.
