low-speed DS1 facility types only. Refer to Figure 4-10.
• SV1A-TL2 with the MP1A-V2 supports TL1/FLEXR interfaces and all
middle-speed and low-speed options. Refer to Figure 4-11.
• SV1A-TL3 with the MP1A-V2 (Issue 06) supports TL1, FLEXR, and Menu
Mode interfaces and all middle-speed and low-speed options. Refer to
Figure 4-11.
• SV1A-TL4 with MP1A-V3 supports TL1/FLEXR, and all middle-speed
and low-speed options, as well as supporting the OC-12 high-speed
interface and the TS1A-ENH unit. Refer to Figure 4-11.
