Cross Connections - Alcatel-Lucent 9500 MPR User Manual

Cross Connections

Cross connection is only required for TDM traffic. Generic Ethernet
traffic is handled automatically via MAC Address learning in the
Ethernet switch. Cross connections can also be used with point-to-
point VLAN Ethernet traffic to direct traffic based on VLAN tag
rather than MAC address.
The cross connections screen is used to configure switching of packetized data through the
CSM (Control and Switching Module - Core) module. Using this screen, the operator can
switch:
• DS1/DS3 (ports) lines from/to a P32E1DS1/P2E3DS3 (PDH DS1/DS3 icons)
module to/from an MD300 (RADIO icons) module and/or any of four Ethernet
(ETH icons) ports on the CSM module.
• Ethernet (ETH icons) data from/to an external source to/from an MD300
(RADIO icons) module and/or to/from a P32E1DS1/P2E3DS3 (PDH DS1/DS3
icons) module.
The screen allows the operator to select DS1/DS3 (PDH icons), Ethernet (ETH icons), and/
or MD300 module (RADIO icons) ports as source and destination ports and provides a
graphical presentation of the switch functions.
Valid Cross Connections:
• PDH to RADIO
– PDH (P32E1DS1 module) to RADIO (MD300 module)
– PDH (P2E3DS3 module) to RADIO
• PDH to ETH
– PDH (P32E1DS1 module) to ETH (Ethernet)
– PDH (P2E3DS3 module) to ETH (Ethernet)
• ETH to RADIO
• RADIO to RADIO
After a cross-connection has been created, two cross-connected slots are visually linked by
a line: a line in the context of this application represents a bundle of flows, which share
same source and destination entity. In addition, all 802.1Q tagged Ethernet traffic having
the same VLAN ID as cross-connection Flow ID number will only be forwarded between
these cross-connected slots.
