The MST4 supports the access of multiple services, alarms, and other maintenance functions.
Table 1 provides the functions and features of the MST4.
Function and Feature | MST4 |
---|---|
Basic functions | Provides four independent ports to transmit/receive multiple services. Supports the transparent transmission of the SAN and Video services. |
Connector type | LC |
Optical module type | SFP |
Service types |
|
Distance extension | The first and second ports support the distance extension function on the SDH side.
|
Maximum uplink bandwidth | 2.5 Gbit/s The backplane provides four 622 Mbit/s buses that are directly connected to the cross-connect unit. The MST4 can adapt to the bandwidth of the slot. |
Mapping granularity | Supports the VC-4-Xc (X = 4, 8, or 16) granularity. |
ESCON services | Transmits/Receives four-channel ESCON services, and the total bandwidth is less than 2.5 Gbit/s. |
DVB-ASI services | Transmits/Receives four-channel DVB-ASI services, and the total bandwidth is less than 2.5 Gbit/s. |
Encapsulation format | Supports the GFP-T protocol, which complies with ITU-T G.7041. |
Maintenance features | Supports inloops and outloops on ports on the customer side, which can be used to locate faults quickly. Supports port-based RMON performance management. |
Alarms and performance events | Reports various alarms and performance events, which can be used to locate faults and maintain the equipment. Supports FC performance measurement only when FC100/FC200 distance extension is enabled. |
