The customer services distributed everywhere such as E1，Ethernet or V.35 services for undertaking, residential community, and government as well as base station are connected to central office access over optical fiber through terminal OMUX and YKSDH-155F series equipments. The equipments with STM-1 interface such as user switch and remoter module are also being connected with tributary unit without transceiver.
SDH/MSTP network is up linked by STM-1 optical interface or electrical interface and data service is accessed with IP metro network by GE or FE Ethernet interface at equipment room. As standard SDH container is mounted on remote SDH transceiver for customer services, various services could be connected across freely through SDH/MSTP backbone network for service transmission within metro area. The service interfaces such as E1，V.35 could also be pulled out from convergence equipments. At customer service center with mass interfaces such as bank branch, public security station, added-value ISPs could be mounted on equipment with service interface Plug-in Cards and accessed to backbone transmission network through STM-1 access operators.
