Full T1 bandwidth
without DSU/CSUs REMS uses the full 1.544 Mbps bandwidth at all points(1.536 Mbps plus
8 Kbps framing). DSU/CSU devices, which add framing and which bit-
stuff to the DTE signal to achieve T1 transmission rates are not necessary.
REMS contains an integral T1 ESF Channel Service Unit (CSU),
permitting direct connection to public or private T1 media. REMS can
also be connected to an existing CSU.
REMS supports B8ZS line coding for network clear channel operation.
Other key
advantages of
REMS The key advantages of Verilink’s patented REMS are:
■
Enhanced security
When compared with the “wraparound” technique, REMS is more
secure for two reasons. First, the frame bit is sent through the
encryptor, not wrapped around. Second, the frame bit is no longer
coincident with DS0 channels. It is randomly aligned with the
payload.
