MANAGEMENT INTERFACES

Telnet, SNMP, TFTP, and SSH over 10/100Base-T

An RJ-45 connector on the backplane of an MX2820 shelf provides a 10/100Base-T Ethernet
interface for the MX2820 system. Through this interface the system connects to an Internet
Protocol (IP)/Local Area Network (LAN) host computer. Each MX2820 shelf requires one IP
address, which can be provisioned with an MX2820 menu option.
The SCU manages the Ethernet interface for the MX2820 system. The SCU controls Telnet,
SNMP, TFTP, and SSH access to each module in the MX2820 shelf.
There is one session reserved for each of the following:
• Craft
• Telnet
• X.25
• RS-485
• SSH
There are also 10 pool sessions that can connect to any of these entities.

NETWORK CONNECTIONS (DS3/STS-1)

DSX-1, DS3/STS-1, and 10/Base-T Ethernet circuits from the
MX2820 are not to be connected directly to outside plant facilities.

Cable Specifications

All coaxial cable for the MX2820 DS3 and STS-1 signals should meet the following minimum
specification:
• The coaxial cable should have characteristic impedance of 75 ohms.
• Nominal mutual capacitance should not exceed 20.4 pF/foot.
• The cable should conform to ANSI standard T1.102 (1993) pulse mask definition. The
standard reference cable is "WECO Type 728A" at 450 feet.
Approved cable types include:
• WECO 728A
• Lucent 728B
• Lucent 734A
• Belden 9231
• Belden 1809A
Lucent type 735A cable may be used up to a maximum length of 250 feet.
