QE1M provides performance monitoring functions, and it will
generate Near and Far end performance parameters for the data it
collects, such as data for Error Second (ES), Severely Error
Second (SES), and Unavailable Second (US). The history data
will record the current ES, SES and UAS information, the ES, SES
and UAS information for the past 8 hours, and also the ES, SES
and UAS information for the past 7 days.
GbE
MSAP2000 provides one Gigabit Ethernet optic trunk interface
(GbE). Besides supporting various Protocols such as IEEE
802.3z, 802.1d, 802.1p, 802.1q, the GbE Module also collects
status, fault, alarms and performance information. The GbE
Module can connect the RT to Ethernet devices directly or serve
as the trunk interface between COT and RT when circuit
emulation for E1 is required, or it can serve as a trunk interface to
connect the COT and RT, to provide broadband services.
4.6. COT Network Interface Module
MSAP2000’s COT provides interfaces for PSTN, Digital Data
Networks, and IP Networks. Its modular design allows network
planning personnel to select the quantity and type of network
modules, based on their own individual requirements.
MSAP2000 can provide connection to PSTN interfaces via analog
2W interfaces (FXO) or V5.2 interfaces. Linkage to a Digital Data
Network is made via 2Mbps E1, and it also has a GbE interface for
connection to IP networks.

FXO
The FXO Module is normally installed within the COT Shelf, and it
provides 16 lines of 2-wire analog voice interfaces for connection
to PSTN Exchange Stations. The functions of FXO include Dial
Ring Detection, Busy tone detection, ringing tone detection, Loop
