- T1 Carrier (1.544 Mb/s)
- E1 Carrier (2.048 Mb/s)
- Cards are suitable for transmission at frequencies up to 5 MHz provided the line is conditioned appropriately. Isolation of 50 kVrms (70 kV peak) its provided while maintaining full communication between terminals
- Communication maintained across the gap by high voltage isolation transformers that provide low-loss low-distortion transmission.
- The 4-Wire T1 Isolator plug-in cards can be installed while power is supplied to a Teleline Isolator shelf.
- Simplex Sealing Current is provided for on the CO side. Sealing Current is not transferred to the Station side
The card can be housed any 4-wire capable 3-card shelf, 5-card shelf, or 8-card shelf, or in any of Positron's pre-configured High Voltage Interface (HVI) units.
