Looking for 739B5 and 739C5. The 739B5, HECI SNRT7E0 (and multiple Comcodes) is a FT-2000 OC-48 Transmitter. The 739C5, HECI SNRT700 (and multiple Comcodes) is also a FT-2000 Transmitter.
The 739B5 and 739C5 are part of the FT-2000 OC-48 Lightwave System, an ADR Multiplexer. The system can support BLSR or UPSR SONET ring protection. The systems may also be known as AT&T FT-2000, Lucent FT-2000, Alcatel-Lucent FT-2000 or even the Nokia FT-2000.
The FT-2000 is a real work horse, with many systems in operation for 20 years. And I am confident that many will still be in operation in another 20! The FT-2000 has been manufacturing discontinued with limited support available, https://support.alcatel-lucent.com/portal/web/support/product-result?entryId=1-0000000000351.
