The interface sockets on the front panel and on the fan-out-panel (FOP) where applica-
ble are connected with the (main) distribution frame or the patch panels using either
patch cables or prefabricated system cables (see "Equipment Overview", page 238).
Prefabricated system cable 4 x RJ45
1)
With terminal cards with 8 or more interfaces, some or all of the RJ45 sockets are as-
signed four-fold on the front panel of the Mitel SMBC. With this cable they can be con-
nected without the use of a fan-out-panel (FOP). The cable is 6 m long and at one ex-
tremity has four RJ45 connectors on which all the pins are wired.
