Hardware Reference 49
C613-03058-00 REV A
combinations of the following PICs (with a maximum of two E1/T1/PRI
cards):
AT-AR020 PRI E1/T1 PIC, one Primary Rate E1/T1 port.
AT-AR021(S) BRI-S/T PIC, one Basic Rate ISDN S/T port.
AT-AR021(U) BRI-U PIC, one Basic Rate ISDN U port.
AT-AR023 SYN PIC, one Synchronous port with universal 50-way
AMPLIMITE connector.
AT-AR024 ASYN4 PIC, four Asynchronous ports with RJ-45 connectors.
AT-AR022 ETH PICs and AT-AR026 4ETH PICs are not recommended for use in the
NSM PIC bays, as performance of these interfaces is likely to be reduced and packet loss
may occur.
AT-AR745 routers have a dedicated PAC slot. PAC slots can accommodate the
following PACs:
AT-AR060 EPAC, Encryption PAC.
AT-AR061 ECPAC, Compression/Encryption PAC.
PACs should only be installed by authorised service personnel. Unauthorised
opening of the router lid may cause danger of injury from electric shock, damage
to the router, and invalidation of the product warranty.
Front and Rear Panels
Front and rear panels of the AT-AR745 router with a PIC installed in each PIC
bay, and an AT-AR040 4-PIC NSM installed in the NSM bay, are shown in
Figure 21 on page 49.
