CHAPTER 1
Cisco ASR 920 Series Aggregation Services
Router Overview
The Cisco ASR 920 Series Aggregation Services Router is a family of fixed configuration routers that
provides common network architecture to the Service Providers for macro and small cell networks.
This router acts as an access device for mobile backhaul services—macro Cell Site Router (CSR) and Small
Cell Router (SCR). As an access device, it provides capabilities like 1GE/10GE, MPLS, H-QoS, Services,
GPS clocking, PoE and fit within ETSI 300 mm depth cabinet. It can easily be integrated into the Unified
MPLS for Mobile Transport (UMMT) and Fixed Mobile Convergence (FMC) solution.
•Cisco ASR 920 Router Features, page 1
•GigabitEthernet Copper Ports, page 2
•GE SFP Ports, page 2
•SFP+ Ports, page 3
•External Interfaces, page 8
Cisco ASR 920 Router Features
The router provides 1GE/10GE, MPLS, H-QoS, high availability hardware design, advanced Ethernet
Operations, Administration, and Maintenance (OAM), as well as advanced timing support, including satellite
timing (GNSS) based clocking, and PoE in one platform.
•ASR-920-12SZ-IM—This router has fixed Ethernet interfaces (8x1G copper + 4x1G SFP + 4x10G/1G
(dual rate)
•ASR-920-12SZ-IM-CC—Has the same specifications as the above variant. However, this chassis is
coated with an acrylic-based material to help improve the reliability against air-borne contamination.
The following table provides snapshot of the number and type of supported ports:

1Each port can operate at either 1G or 10G, and operates in a mutually exclusive way. You cannot insert both 1G and 10G together. If you insert IG IMs
(A900-IMA8T1Z, A900-IMA8S1Z, A900-IMA8T, A900-IMA8S), the dual rate port would support only 10G.
GigabitEthernet Copper Ports
Fixed copper GigabitEthernet (GE) interfaces are provided through standard RJ-45 connectors. These ports
support the following features:
•Standard 100/1000Base-T/TX operation with forced or auto-negotiation for speed and duplex.
•Automatic crossover (auto-MDIX) for straight-through and crossover connections.
•Pause flow control as defined by the 802.3x standard.
•Frame size of 9216 bytes.
•Synchronous ENET operation that provides its recovered receive clock as an input clock source for the
SETS as well as uses the system-wide reference clock to derive its transmit clock.
GE SFP Ports
The GE SFP ports support the following features:
•100Base-FX and 1000Base-X SFP modules.
•Digital optical monitoring as specified by the SFP.
•Any mix of SFPs is supported unless specifically noted.
Smart SFPs are not supported on the router.Note
•Pause flow control as defined by the 802.3x standard.
•Frame size of 9216 bytes.
•Synchronous ENET operation that provides its recovered receive clock as an input clock source for the
SETS as well as uses the system-wide reference clock to derive its transmit clock.
Copper based SFPs do not support synchronous ENET operations.Note
