Dialing and paging between TC8638-1 (FXS) units is supported, providing customers flexibility for voice calls. It is economical, easy to install and comes standard with built-in power redundancy.

  • 4-ch. FXS (TC8638-1) or 4-ch. FXO (TC8638-2)
  • Mux 4 ch. 2-Wire Telephone/Fax/Modem over T1/E1
  • 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 or 1S Standalone Chassis
  • 12VDC, 24VDC, -48VDC, 125VDC
  • “R2” Push Button for Troubleshooting Local Or Remote Units

The TC8638 is available in two configurations:

  • 4-Channel FXS (TC8638-1)
  • 4-Channel FXO (TC8638-2)

With two TC8638 cards in one 1U chassis, there are two T1/E1 connections available for following configurations:

  • One 8-channel voice multiplexer, T1/E1 primary link and T1/E1 secondary link (in TCRM19F-R chassis).
  • Two 4-channel voice multiplexers, each having their own T1/E1 connection (in TCRM19F-I chassis).
