When HandyTone-386 is out of power, the RJ 11 line jack on the HandyTone-486 side will function as
a pass through jack. The user will be able to use the same analog phone for PSTN calls.
5.4 FAX Support
HandyTone-286 supports FAX in two modes: T.38 (Fax over IP) and fax pass through. T.38 is the
preferred method because it is more reliable and works well in most network conditions. If the service
provider supports T.38, please use this method by selecting Fax mode to be T.38. If the service
provider does not support T.38, pass-through mode may be used. To send or receive faxes in fax pass
through mode, users will need to select all the Preferred Codecs to be PCMU/PCMA.
