TC8738E
4-24 Channel FXS/FXO-over- T1/E1 Channel Bank
Features
The TC8738E is a 4-24 channel Voice/Fax/Modem channel bank that allows network managers the flexibility of leveraging T1/E1 circuits by adding low cost telephone lines as needed. With four ports per TC8738 card, up to six can be combined to form a 24-channel channel bank. Compatible with most standard channel banks. The device is economical, simple to install and comes standard with built-in power redundancy.
The TC8738E is available in two configurations:
- 4-Channel FXS (TC8738E-1)
- 4-Channel FXO (TC8738E-2)
- Channel Bank Replacement
- 4-24 ch. FXS (TC8738E-1) or 4-24 ch. FXO (TC8738E-2)
- Mux 4 ch. 2-Wire Telephone/Fax/Modem over T1/E1
- T1/E1 Status LEDs: BPV, LOS, SYNC, RAI, AIS, CRC
- Compatible with most standard channel banks
- ESF and SF Framing Support for T1
- PCM30 and PCM30C Framing Support for E1
- Power Redundancy Standard
- 1U Rack Mount Chassis
- 12VDC, 24VDC, -48VDC, 125VDC
- “R2” Push Button for Troubleshooting
- Standard 5-year Warranty
The TC8738E is placed into the TCRM19H 1U rack, which can hold up to two TC8738E cards. If two cards are fitted to the rack, then they may be configured in two ways:
- Individual Operation: Each card operates independently withing the 1U chassis and connects to its own T1/E1 connection
- Daisy-chain Operation: Each card operates is connected to the next so that both cards can utilize the T1/E1 connection. (See Applications for more details.)
Applications
A low cost and immediate solution, the TC8738E 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.
A legacy and end of life channel bank replacement.
Multi-Card Operation:
The TC8738E is placed into the TCRM19H 1U rack, which can hold up to two TC8738E cards. If two cards are fitted to the rack, then they may be configured in two ways:
1. The cards are configured for individual operation
Here, each card operates independently and connects to its own T1/E1 connection.
2. Daisy-chain operation
With daisy chain operation, each card is connected to the next so that both cards utilize the T1/E1 connection.
Daisy chaining these together means an eight-port voice module is connected utilizing the same T1. An internal rack connection means only inter-rack connections are required.
If required, multiple 1U racks can be daisy-chained together to build up to a 24-channel unit, all using the same T1/E1.
