• DS3–TDM (HNS 1027094–0001)
• Universal–DS1 (HNS 3003132–0001)
• DS3–ATM (HNS 3003136–0002)
• DS3–Transparent (HNS 1027094–0002)
The following RT SSIs are currently in development:
• MPEG
• Ethernet 10BaseT/100BaseT
SSIs are installed in slots 2 through 5 in the RT IDU chassis.
The Quad–DS1 SSI, shown in figure 3-15, provides up to a four
