Telco Line Bridge (TLB) Rackmount Card  

Send data to four leased lines with one modem.


Extended Double Diamond™ Warranty Available (3 Additional Year)

Product Highlights

  • Consolidates your leased lines so you don’t have to pay for a multipoint leased line. You keep control and save money.
  • Use in local and remote networks.

  • Further Details

    With the BLACK BOX® Telco Line Bridge, you can consolidate your leased lines as a cost-saving alternative to paying for multipoint leased line services.

    Flexible enough to work locally or remotely, the Telco Line Bridge can go wherever the best place is to bridge your leased lines. The TLB distributes a 600-ohm line impedance to each extended line. Varying line conditions and lengths are no problem—you set the gain or attenuation of each port separately so you can tune each port to the conditions of the line it handles.

    If you manage multiple leased lines, you can keep your setup organized and free from cable snarls—simply use the rackmount version(s) of the TLB and our 8-Card Rack.
