The TC8638 is a 4-channel Voice/Fax/Modem over T1/E1 Multiplexer that allows network managers the flexibility of leveraging T1/E1 circuits by adding low cost analog as needed.
Dialing and paging between TC8638-1 (FXS) units is supported, providing customers flexibility for voice calls. The device is economical, simple to install and comes standard with built-in power redundancy.
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).
- 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
A low cost and immediate solution, the TC8638 is typically used to link analog telephones or legacy dial-up devices including data modems, fax machines, meters, ATM, and credit card machines over T1/E1.
