In the late 2010's volunteer æstrid Smith wired up the [[Pretranslator]] (PRT) to allow the machine to translate on a varying number of dialed digits. (Before this was returned to service, a museum caller could not dial common three digit codes, like 411, 511, etc. They had to dial a full 7 digits, like 511-1111 in order to complete their call). At the same time, æstrid and Sarah Autumn configured the machine to place calls to the [[C*NET|C*NET collector network]] via [[CMS:Kercheep|kercheep]] using 1+7D dialing. | In the late 2010's volunteer æstrid Smith wired up the [[Pretranslator]] (PRT) to allow the machine to translate on a varying number of dialed digits.

In 2021, volunteer Sarah Autumn fully repaired the [[trouble recorder]], which had not been working for several years. This was a substantial addition to the switch, as the trouble recorder was one of the primary diagnostic tools used by technicians. | In 2021, volunteer Sarah Autumn fully repaired the [[Trouble Recorder|trouble recorder]], which had not been working for several years.

In 2022, Sarah brought up the [[Automatic Number Identification|ANI]] frames, which allow the 5XB to outpulse the calling number to the [[CMS:Kercheep|kercheep]] tandem. For example, dialing KE7-1111 from the 5XB will cause kercheep to read back the phone number of the calling telephone which is sent out from the 5XB during the call setup process. | In 2022, Sarah brought up the [[Automatic Number Identification|ANI]] frames, which allow the 5XB to outpulse the calling number to the [[CMS:Kercheep|kercheep]] tandem.
