Persiapan
untuk instalasi.
Instalasi
Router,
Diasumsikan
bahwa Router sudah terinstall dan tersambung dengan menggunakan satellite dan diasumsikan
koneksi tidak ada gangguan apa-apa dan berjalan dengan baik. Diasumsikan
langganan bandwidth sebesar 128 Kbps both Upstream dan Downstream untuk kedua
site. Dan
dipakai untuk private network atau jaringan tertutup didalam perusahaan (
seperti halnya leased line) dan
diasumsikan bahwa kebutuhan internet di kantor remote memakai akses internet
yang sama / shared dengan
yang ada dipusat.
Topologi
jaringan VoIP via Satellite.
A.
Konfigurasi Router HeadQuarter :
Diasumsikan
bahwa 3 Voice Port tersambung ke PSTN Direct Line ( menggunakan 2 buah VIC- 2FXO
), yaitu :
-
Voice-port 1/0/0
-
Voice-port 1/0/1
-
Voice-port 1/1/0
Dan
1 Voice-port disambung ke PBX yang ada dipusat, sehingga orang-orang yang ada
di job site bisa langsung men-dial nomer Extension rekannya yang ada dipusat,
Voice-port tersebut yaitu Voiceport 1/1/1. Untuk
detail konfigurasi router HQ bisa dilihat pada capture show run berikut ini :

B.
Konfigurasi Router Remote Job Site:
Diasumsikan
bahwa 3 Voice-port ( 2 Buah VIC-2FXS ) tersambung ke PBX local yang ada di Job
Site dan

dipusat (HQ).
3
Voice-port tersebut adalah
-
Voice-port 1/0/0
-
Voice-port 1/0/1
-
Voice-port 1/1/0
1

merupakan nomer
extension
yang ada didaerah dan tersambung langsung melalui VoIP Peer dengan PBX yang ada
di
kantor
pusat (HQ). Berikut
