GND Logic Ground Common
where n is the port number.
3.3.11 DECconnect Style Modular Splitters
Eight-port and 24-port DECconnect style modular splitters with type MMJ connectors are
available. The splitters are similar to that shown in Figure 3-15. The 8-port splitter requires 1
DECconnect adaptor extension; the 24-port splitter requires 3 DECconnect adaptor extensions.
