Perkembangan Teknologi VoIP  Voice Only ToIP  Voice + Signaling + PSTN IPTel  ToIP + Internet Addressing Tantangannya … Mampukah pemerintah mengontrol IPTel?

Contoh Real di Selular Ref: 4G the end of intelligent network, dana blair (dblair@cisco.com)

Base Station Controller Mobile Switching Center (MSCA) 2G to 4G Voice Delivery Base Station Controller Mobile Switching Center (MSCA) 2G PSTN BTS ISDN w/ handoff Circuit Node B MSC Server RNC 3G R’99 ATM ISDN w/ handoff 3G R’00 VoIP Node B Call State Control Function SIP Call stateful Proxy SGSN RNC ATM IP Tunnel GGSN Internet Node B 4G VoIP IP SIP Media Gateway

Base Station Controller Mobile Switching Center (MSCA) 2G to 4G Data Base Station Controller Mobile Switching Center (MSCA) V.110 NAS 2G BTS ISDN w/ handoff PSTN Circuit Internet Node B SGSN 2.5G GPRS RNC ATM IP Tunnel GGSN Node B SGSN RNC ATM IP Tunnel GGSN 3G UMTS Node B 4G IP 3G data delivery is the same as 2.5G

Kesimpulan sementara Selular jelas-jelas akan menggunakan internet telephony (SIP) & IPv6 untuk generasi 4G. Selanjutnya, mari kita lihat infrastruktur rakyat!

Pertanyaan .. Numbering? .. Addressing? Infrastructure Deployment? Sentral telepon? Handset? .. PC? .. Iptel device? Tantangan untuk pemerintah .. Bolehkah? Perlukah ijin?

Infrastructure Deployment? Topologi Sederhana Infrastructure Deployment?

Pembangunan Infrastruktur? Tahun 2000 Jaringan akses - US$50-100/line s/d sentral telepon terdekat. Jaringan regional - US$86/line/bulan. Telkom US$1000/SST.

Pembangunan Infrastruktur? Tahun 2001 Card WLAN 11Mbps US$150 (687 line) 1 unit gateway WLAN 11Mbps US$700 (687 line) ~ US$1 / line Tahun 2002 2-3 bulan lagi akan beroperasi WLAN 54Mbps (3375 line), harga US$250-an.

Pembangunan Infrastruktur? Jaringan swadaya masyarakat - investasi/line menjadi beberapa cent US$/line. Bolehkah? Perlukah ijin?

Topologi Sederhana Sentral Telepon?

Sentral Telepon PC based, komputer based Mengenali nomor telepon .. Open source Open standard Price US$0, US$100, >US$1000 Setiap rumah, setiap RT, setiap kantor, setiap orang bisa memasang sentral telepon sendiri!

Sentral Telepon Bolehkah? Perlukah ijin? Maukah pemerintah mengalokasi nomor telepon kepada infrastruktur swadaya masyarakat? Jika tidak mau, no problemo man  …

Topologi Sederhana Device?

Device? Handset OK FAX machine OK PC OK Iptel device OK Video OK Remote sensing OK Bar code OK Dll ….. OK

Device? Bolehkah? Perlukah ijin?

Topologi Sederhana Numbering? Addressing?

Numbering? Addressing? Versi lama – nomor telepon. Versi baru +62 21 765 4321 (full control pemerintah) Versi baru sip:onno@indo.net.id sip:+62-811-85-2542@sipgate.net.id (mampukah pemerintah mengontrol?)

Numbering? Addressing? Internet telephony addressing menjadi superset (bukan subset) dari telepon. Mampukah pemerintah mengontrol internet telephony addressing? Bolehkah? Perlukah ijin?

Kesimpulannya … Numbering? .. Addressing? Infrastructure Deployment? Sentral telepon? Handset? .. PC? .. Iptel device? Mampukah pemerintah mengontrol isu di atas? Jika ya, mana peraturan / perundangannya? Jika tidak, perlukah rakyat ditakuti?

Kesimpulan Keberhasilan Infrastruktur … Kompetisi Level Playing Field Interkoneksi Mampukah pemerintah menset koridor yang di perlukan?
