Installing a RADWIN MHS

Note
In what follows, it will be assumed that –
1. We will depart from our usual Site A / Site B conventions. Sites A and B on the primary link
will be Sites 1.2 and 1.4 respectively. The corresponding sites on the secondary link will be
Sites 2.2 and 2.4. The site names reflect their IP addresses. This is a useful convention and
is reflected in the screen captures below.
2. The link will be managed from Site 1.2; Site 1.4 may be a remote site.
3. The links intended as the primary and secondary will be referred to their respective names,
Primary Link and Secondary Link as shown in
to be installed.

To install a Hot Standby Link:
1. Set up Primary Link in the usual way. Ensure that it is fully operational in accordance
with the relevant instructions in Part 1 of the User Manual.
Do not proceed unless this condition is fully met!
Note
2. Connect user equipment to Site 1.4.
3. At Site 1.2, disconnect the TDM cables from the external equipment or disconnect
external equipment from the Hot Standby Patch Panel.
4. The HSS cable (connecting the ODUs) should be connected at Site 1.2. The ODU
belonging to the primary link should be configured as HSM, whereas the ODU
belonging to the secondary link should be configured as HSC-CT.
5. Establish Secondary Link in the usual way, with HSS enabled. The two link fre-
quencies should be at least 5MHz apart.
WinLink 1000 User Manual
• With RADWIN 2000 links you can protect up to 16 TDM ports. To pro-
tect more than eight TDM ports use two Patch Panels at each site.
• Ethernet services are carried independently by primary and second-
ary links. Each link carries different Ethernet traffic. MHS does not
protect Ethernet traffic.
