B.5.3 TXP_MR_2.5G and TXPP_MR_2.5G Card Specifications
The TXP_MR_2.5G and TXPP_MR_2.5G cards have the following specifications:
• Line (trunk side)
– Bit rate:
2.488 Gbps for OC-48/STM-16
2.66 Gbps with ITU-T G.709 Digital Wrapper/FEC

Caution You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the TXP_MR_2.5G
and TXPP_MR_2.5G cards in a loopback on the trunk port. Do not use direct fiber loopbacks
with the TXP_MR_2.5G and TXPP_MR_2.5G cards. Using direct fiber loopbacks causes
irreparable damage to the TXP_MR_2.5G and TXPP_MR_2.5G cards.
