E1/PRI interface specifications
The MAX unit’s E1/PRI interface has cabling and port specifications. During loss of power or
whenever the MAX restarts, a relay closure returns the E1/PRI signal to the WAN. That is, the
E1/PRI line is looped back. However, if you configure the MAX for framing-compatible
drop-and-insert functionality, all channels of line #1 are passed to line #2. Note that line #1 and
line #2 of a MAX Net/E1 expansion module always loop back upon loss of power, regardless
of how they are configured.
E1/PRI cable specifications
The WAN interface cables and plugs described in this section are available for the MAX unit’s
WAN interfaces. Use only the cable specifically constructed for transmission.
