....as errored and an anomaly is raised (refer to [4] R38) Reserved Field (R) shall contain the octet pattern of 01101010 (6A hexa) which is the same as that of the idle cells. 3. PMD for the 622 Mbit s interface Currently, three fiber based PMDs are defined for the 622.080 Mbit s interface [7]. Other PMD types are for further study. A single mode fiber interface and two multi mode fiber interfaces are defined. The support of either longer link distances or other fiber types is based on the chosen implementation. R39) The public UNI shall use the single mode interface. 622 and 2488 ....
....interface. O2) The private UNI and the private NNI may use either multi mode interface. The physical media consists of two fiber links, one for each direction of transmission. 3.1. Single Mode fiber interface (R40) This interface shall be as specified in 2.1. 1 of AF PHY 0046.000 specification [7]. 3.2. Multi Mode fiber interface (R41) This interface shall be as specified in 2.1.2 of AF PHY 0046.000 specification [7] 3.3. Synchronisation (R42) Interface synchronisation shall be as specified in 2.1.3 of AF PHY 0046.000 [7] 3.4. Media interface connector (R43) Media interface ....

....to SDH network elements which perform the Multiplex Section protection function and those systems in the TMN which manage SDH network elements. Functional capabilities of SDH multiplex equipment, particularly the Multiplex Section protection switching function, are given in Recommendation G. 783 [49]. Performance monitoring requirements for Multiplex Section protection (for the management of SDH equipment with this capability) are provided in Recommendation G.784 [61] however, the information model which supports these can be found in Recommendation G.774.01 [57b] MIB Extensions for ATM ....
