3.3.2 Ethernet Redundancy with CRS-300

After the customer has determined the best configuration for near-to-far end Ethernet networks,

the CRS-300 1:10 Redundancy Switch may now be added to one or both ends of the link(s).

Ethernet redundancy using the CRS-300 can be accomplished using a wired-thru or

wired-around configuration.

3.3.2.1 Wired-thru Connection

MPORTANT

This redundancy approach is the recommended and preferred

connection method.

The wired-thru Ethernet connection on the CRS-300 is the easiest and simplest choice for Ethernet

redundancy. This connection method – the same as used on the standard serial data interface –

provides a single connection for the User Data Interface and provides simple form-C relays that

route the Ethernet connection from the User connection to either the Traffic or Redundant Modem.

3.3.2.2 Wired-around Connection

MPORTANT

While this redundancy approach is not recommended, it can be used

after study of the LAN and WAN sides of the IP networks.

The wired-around Ethernet connection is used with the CRS-300 and the CDM-700 modem

where both modem data interface slots are needed; e.g., where one slot is HSSI or G.703 and the

other slot is GigE. With the Ethernet slot configured for the wired-around method, this gives full

redundancy capability to both data slots. However, care must be taken to ensure there are no

Ethernet network loops or connection problems – this method should only be used if both modem

data slots are used. In general, the wired-around approach can be used in a hub-to-remotes

configuration with standard traffic.
