CMS has evolved over the years and so has our marketing. This shot showcases some of our original phone book and Yellow Page advertisements that we’ve put out over the years.

Examples of an older model telephones.

This is a bank of PRI/T1 interface cards that we used to utilize for bringing in DS0 voice channels. Each card handled 24 channels, 23 of which were used for voice communications (B, or bearer channels) and the 24th, called the D (data) channel, which handles call control and signaling.

Two more examples of older telephones.

This is a 4 line switchbox (cord board) that you could connect up to 4 extensions off of. No it’s not a toy, but it sure looks like one.

This shot showcases another of our original advertisements along with an old-style handset receiver.

A large cord board (telephone switchboard, or manual exchange) that would connect groups of telephones to an outside line.
