Black Box Distribution Panel for Cisco High-Density Analog and Digital Extension Module for Voice and Fax Network Accessory

The panel consists of eight RJ-11 connectors (labeled BASE) for connection to analog phones. It also has 16 RJ-11 and 8 RJ-45 connectors on the panel's center and right sides (labeled EM0 and EM1) for connection to digital phones, faxes, and modems. The center and right-side connectors have a sliding plate that enables you to choose either the top (RJ-11) or bottom (RJ-45) row of connectors for use. Select the connectors you will use by sliding the connector cover over the unused ports. (NOTE: Do not plug cables into the center top [RJ-11] and bottom [RJ-45] or the right-side top [RJ-11] and bottom [RJ-45] connectors at the same time. The sliding panel prevents this from happening.)

Four combinations of connectors are available, depending on which connectors are covered with the sliding plate. Link up to eight analog phones via RJ-11 cable (EL06M-MM) to the connectors labeled BASE on the panel's left side, and attach 8, 12, or 16 digital Internet phones, fax machines, or modems via RJ-11 (EL06M-MM) or RJ-45 cable (EVNSL51) to the connectors labeled EM0 or EM1 on the panel's right side.
