Card Variants
There are 8 variants based on:
• Primary rate interface (T1 or E1)
• AAL type (AAL1 or AAL1/AAL5)
• System backplane bandwidth 
(4 Mb/s or 16 Mb/s)
• EMC compliance 
ATM Service Adaptation
• AAL1 and AAL5
• Selectable on a DS0 basis for 
channelized user-side interfaces 
(e.g., T1/E1)
AAL1 Adaptation and CES 
• AAL1 or AAL1/AAL5
• Adapts CBR data and associated 
signaling (n*64 kb/s) to AAL1 
VCs over an ATM network, in 
accordance with AF-SAA-
0032.000 and GR-1113- CORE
•DS0s 
¬ Supports up to 84 for T1
interfaces 
¬ Supports up to 104 for E1
interfaces 
¬ Multiple DS0 CESs can be
transmitted over the same VC
¬ Voice (LGS) and data (V.35)
DS0s with a common desti nation can be transmitted 
together
• Configurable signaling multi frame size: 16 or 24 frames
• Supports voice signaling with 
robbed-bit signaling and channel 
associated signaling
• Received cell delay variation 
tolerance is user defined per VC
• Transmit cell level is user defined 
per VC from n to 47, in one byte 
increments, where n is the number 
of DS0s in the VC 
AAL5 Adaptation and 
HDLC Services 
• AAL1/AAL5
• Transports HDLC-formatted 
traffic over an ATM network
• Transparently adapts streams 
of HDLC frames into AAL5 VCs
• Interworks and adapts streams 
of frame relay HDLC frames into 
AAL5 VCs
• Supports up to 3,968 Kb/s of 
HDLC-formatted traffic 
Interworking Mode
• Supports service interworking 
mode (translates frame relay into 
ATM, for transmission across an 
ATM network to ATM devices)
• Supports network interworking 
mode (transports frame relay 
across an ATM network to 
another frame relay network)
• Compliant with FRF.5 and FRF.8 
using AAL5 and non real-time 
variable bit rate (nrt-VBR) or 
unspecified bit rate (UBR) 
Data Link Connections 
(DLCs)
• Supports up to 250 DLCs per 
stream
• Supports up to 1,024 DLCs per 
card
Connection Admission 
Control (CAC)
• Static and dynamic
• Based on: 
¬ Peak information rate (PIR) 
¬ Sustained information rate (SIR) 
¬ Minimum information rate (MIR)
ATM Traffic Management
