For FOM-4SF with V.24, V.35, RS-530 and X.21 interfaces, the local loopbacks take priority over remote loopbacks requested from the remote modem. For FOM-4SF with E1 and T1 interfaces, the local modem can run a local loopback at the same time that the remote modem initiates a remote loopback (see Figure 5). Figure 5.
