LO Procedures for operation of termináis in restricted networks Jnder study; the followíng subclauses give preliminary considerations. rerminals connected to a restricted network shall transmit the BAS capability "restricted" (100) [22] continuously ivhen receiving an incomíng A = 1 at the start of a cali. LO.l Network aspects !n this Recommendatlon the term "restricted network" applies to a network havíng restricted 64 kbit/s transfer ;apability, defined m Recommendatlon 1.464 as 64 kbit/s octet-structured capability with the restriction that an all-zero >ctet is not permitted. LO.2 Reference connections LO.2.1 Case 1: 56 kbit/s, V.35 interfaces Diagram a) of Figure 5 shows a reference connection by a 56 kbit/s data service using V.35 interfaces. A 56 kbit/s clock s available at the V.35 ínterface; 8 kHz clock is not assumed. Diagram c) of Figure 5 shows a reference connection, ¡onnected by 56 kbit/s network service with network clock. LO.2.2 Case 2: n X 56 kbit/s, V.35 interfaces Diagram b) of Figure 5 shows a reference connection with more than two 56 kbit/s connections. Frame alignment wíll >e according to Recommendation H.221. Neither septet timing ñor septet alignment is assumed. Diagram d) of Figure 5 ihows a múltiple n X 56 kbit/s without septet alignment or septet tirning. LO.2.3 Case 3: n X 64 kbit/s with octet timing and alignment Diagram e) of Figure 5 shows a reference connection consisting of two visual telephones connected by facilities >perating in a private Une environment. Unrestricted mode of operation is not assumed. LO.2.4 Case 4: H0 (384 kbit/s) operation ÍVhen working in a restricted network a "1" shall be placed ín the eighth bit position of every octet of every time-slot; he service channel is then in the seventh bit. LO.2.5 Case 5: 56 kbit/s satellite operation "or further study. LO.2.6 Case 6: 56 kbit/s interconnecting a 64 kbit/s network V 64 kbit/s terminal will interwork with a 56 kbit/s terminal as a rate adapted data cali over a 64 kbit/s bearer channel, rhe terminal connected to the 64 kbit/s connection will rate adapt according to Recommendation H.221. In the case of [64 kbit/s terminal connected to ISDN, the terminal may optionally be equipped to intercommunicate through an SDN V.35 terminal adaptor, In any case, because the 56 kbit/s terminal cannot transmit correctly aligned septets, the erminal at the 64 kbit/s end cannot assume septet timing. L0.3 Transmission formáis LO.3.1 Framing signal (56 kbit/s) rhe transmission shall be arranged in 80 septet frames as specified in Recommendation H.221. LO.3.2 Transmission formats (56 kbit/s operation) n 56 kbit/s operation the septets of each 7 X 80 bit frame will be transmitted in order, most significant bit first at the i6 kbit/s rate. Septet alignment will be recovered from the frame alignment signal as specified in Recommeniot;~n TJ 001
