4E1 can be add/dropped by TN 6p/TN 2p. TN 20p can add/drop 8E1 by default. Enough for 2G site. Rest all E1’s (maximum up to 380E1’s) can be cross connected by software patching. Passed transparently. No messy cabling.Two FE ports provided in TN. One for Traffic and one for DCN.SFP interface (Electrical/optical) for SDH MMU’s
