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,
