7.2. ECC (Embedded Communication Channel)
For communication over a link the ECC channel in the radio-frame is used. The capacity of the ECC
channel is 256 kb/s.
7.2.1. IP Routing
The Supervisory system contains a routing function that enables routing of TCP/IP and UDP/IP traffic
between the various management interfaces such as the Ethernet interface and the ECC channel. The
routing protocol used is OSPF/RIP2. This enables both transport of Evolution Series management traffic
as well as other telecom equipment IP based management protocols.
7.2.2. Embedded SNMP agent
The embedded SNMP agent supports the following management functions.
• Basic monitoring of network and interface parameters
• Fault Management
Supports enumeration of possible alarms, current alarm table and historic alarms (log).
• Analogue measurements
Received signal level.
• Performance measurements
7.3. Interfaces to the supervision system
7.3.1. General
Four external interfaces are available for the supervision system.
LAN interface Two 10/100BASE-TX interfaces, IEEE 802.3 Full Duplex.
Connector type: RJ-45
USB interface Two USB ports are available, one host and one device. The host port serves as
LCT interface.
7.3.2. LEDs
