NTBA split

Network termination for ISDN access

with integrated ADSL splitter

Field-proven

Fail-safe

Hassle-free

The NTBA split connects ISDN customer premises equipment to the public ISDN network. Additionally, the NTBA split separates the ISDN signal from ADSL signal allowing the transmission of both signals via ISDN UK0 port. That enables subscribers to digitally transmit voice and data over the ISDN access line, and to connect the ADSL modem directly to the NTBA split. The ISDN access line is linked via ISDN UK0 port. Two ISDN S0 ports are available to connect up to 8 terminal units, e.g. ISDN telephones or ISDN PC cards. The U-R2 port is available for an ADSL modem.

  • Two independent Basic Channels (B Channels) each with 64 Kbit/s
  • One 16 Kbit/s Signaling Channel (D)
  • Bidirectional transmission speed: 144 Kbit/s
  • Two services can operate simultaneously
  • Up to 8 ISDN access sockets via two ISDN S0 ports
  • U-R2 port (annex B) for ADSL modem
  • Industry standard 4B3T line code for ISDN UK0 port
  • Echo cancellation at ISDN UK0 port ensures bidirectional data transmission
  • Quick configuration thanks to accessible DIP-switches
  • Compact housing (150 x 110 x 45 mm)
  • Low susceptibility to interferences
  • Power supply via ISDN UK0 port or locally

APPLICATIONS

Basic voice communications with two or more simultaneous connections, including data and fax

ISDN video conferencing

Broadcasting industry – reliable audio connection from covering point to broadcasting point

ISDN PBX – making outgoing and receiving incoming calls from any phone in the organization

Back-up Internet connectivity – automatic fail-over to the ISDN network for accessing Internet when the primary Internet line, e.g. Internet leased lines, broadband is down

Bank ATM / point of sale locations – ISDN networks make a good choice for connecting critical yet low bandwidth consuming applications, e.g. multiple Bank ATMs, point of sale locations which needs network access for accepting payment through credit cards
