The Visual UpTime® Select™ X.21 LinkSafe™ inline
probe ASE is deployed inline on an access line, typical-
ly between a CSU/DSU and customer premises equip-
ment (CPE). It supports Multi-Protocol software for
deployment in standard frame relay or HDLC networks
and IP Transport software for deployment in frame
relay or HDLC-based networks that use IP switching.
The ASE supports X.21 connectivity through a X.21
Data Terminal Equipment (DTE) interface on the
network side and Data Communications Equipment
(DCE) interface on the user side.
The ASE operates at data rates up to 2.048 Mbps,
deriving timing from the network-side and sourcing
timing on the user side. It also includes LinkSafe
technology to protect circuit integrity in case of an
ASE outage, as well as power failure notifi cation.
