SAEs
Size Alteration
– SAE 442 (max NI=512K, steps of 16K)- XMV=0,1– SAE 600 blocks CH and XM (subrate traffic, max
NI=128K)- XMV=1
• An AP is an access point where one Unit connects to another
• XM has 22 APs 0 - 21 !DL34!• MUX34 has 4 APs 0 – 3 !DL3!• MUX3 has 16 APs 0 – 15 !DL2!
APs
MUPs
• New commands– For example: GDCOI, GDCOE, GDCOP, GDCVP,
GDSTP,GDBLI/E,GDTEI
