Features

The TC8631-4 is a 2 or 4 Channel RS-232 Sync-over-T1/E1 central directional multiplexer. Using two DB9 female ports (Port 1 & Port 2) for RS-232 Sync signals and each channel supports up to 28.8 Kbps. It features three different types of built-in loopbacks: local, remote, and T1/E1 loopback, and can assist in isolating whether an issue lies on your serial line or your T1/E1 line. CSU Loop Code Up/Down is also supported.

  • 2 CH or 4 CH RS-232 Sync with Full Handshakes (CTS/RTS, DTR/DSR)
  • Built-in Internal Clocks (TXC/RXC)
  • RS-232 Status LEDs for 8 Signals: TXD/RXD, CTS/RTS, DTR/DSR, TXC/RXC
  • Seven LEDs for T1/E1 Status BPV, LOS, SYNC, AMI, RAI, AIS, CRC
  • ESF Framing Support for T1
  • PCM31C Framing Support for E1
  • Very Low Latency
  • Optional Power Redundancy
  • 1U or 4U Rack Mount
  • 12VDC, 24VDC, -48VDC, 125VDC, 100-240VAC
  • “R2” Push Button for Troubleshooting Local Or Remote Units

Using two DB9 female ports (Port 1 & Port 2) for RS-232 Sync signals and each channel supports up to 28.8 Kbps.

With two TC8631-4 cards in one 1U chassis, there are two T1/E1 connections available for following configurations:

  • Two 2 channel serial RS-232 multiplexer, each having their own T1/E1 connection
  • One 4 channel serial RS-232 multiplexer, T1/E1 primary link and T1/E1 secondary link

The TC8631-4 is ideal for applications where RS-232 Sync serial data needs to be extended over a T1/E1 link.

Applications

The TC8631-4 2-Channel RS-232 Sync-over- T1/E1 multiplexer provides an inexpensive method for connecting terminals such as relays, and status collecting devices. It is also used in harsh environments where EMI/ RFI interference, ground loops and lightning conditions may exist.
