Kercheep is a computer that lives in the 1XB. It runs Debian Linux and performs several important functions for the museum. Kercheep is administrated by Sarah and Matt.

History

Kercheep was originally a much older PC named "tray", which was set up by æstrid Smith in the early 2010s. Sarah later upgraded it, and renamed it to "kercheep" after a birdlike sound made by a tandem switch connecting a call over 2600hz supervised trunks.

It contains two T1 cards with 4 spans each, for a total of 8 T1 spans, or 192 voice channels.

It is running a custom kernel, compiled by Matt, and a custom version of Asterisk and DAHDI with the following notable modifications:

• hearpulsing is enabled
• Revertive Pulse signaling is supported
• Feature Group C CAMA has been patched to make 1XB ANI-B actually work (note this patch has since been merged into Asterisk main)

Functions

Kercheeps functions are as follows:

• runs panel_gen, the museum call simulator
  • also provides an HTTP server and REST API for the call simulator controls
• runs Asterisk / DAHDI for interoffice trunking and tandem functions
  • is the host for the KE-7 tandem office
  • provides an ANAC at 537-1111 for switches that support ANI-B
  • provides coin announcements and a recorded museum welcome message
  • allows us to dial calls to and from C*NET and Phreaknet
