1 FXS + 1 FXO Hybrid ATA with PSTN Failover
The Grandstream HT813 is a hybrid analog adaptor with both an FXS and an FXO port, letting a site connect an analog phone and keep a PSTN line as backup. Its PSTN lifeline failover means calls can still be made or received over the landline if the network or power is interrupted — with HD voice, T.38 fax and enterprise security.
