CISCO SPA122 ATA WITH ROUTER
(134033986)
Το Cisco SPA122 ATA με router,συνδιάζει την λειτουργία VOIP με ένα εσωτερικό router για ενσύρματη LAN σύνδεση. Εύκολο στην εγκατάσταση και στην χρήση, λειτουργεί σε ένα IP δίκτυο για να συνδέσει αναλογικές συσκευές τηλεφώνου και φαξ σε έναν πάροχο VOIP και προσφέρει επιπλέον υποστήριξη για συνδέσεις LAN. Το Cisco SPA122 διαθέτει 2 θύρες τηλεφώνου, 2 θύρες 100BASE-T RJ-45 Ethernet για συνδέσεις WAN και LAN. Η κάθε τηλεφωνική γραμμή μπορεί να ρυθμιστεί ξεχωριστά.
