● 802.11b 20 dBm
● 802.11g 17 dBm
● 802.11n 16 dBm
● CDMA: 850 and 1900 MHz
● HSDPA: 850, 900, 1800, 1900, and 2100 MHz
● ST-Microelectronics 20190 Chipset.
● Supports ADSL over basic telephone service with Annex A and Annex B ITU G. 992.1 (ADSL),
G.992.3 (ADSL2), and G.992.5 (ADSL2+).
● Supports ADSL over basic telephone service with Annex M (except UK Mask) (extended
upstream bandwidth) G.992.3 (ADSL2) and G.992.5 (ADSL2+).
Cisco 887-M is optimized for PSD Mask EU-64 M9.
◦
Cisco 887M supports UK Annex M only with Huawei 5300 DSLAM and its EADB line card
◦
with customer-premises-equipment (CPE) firmware Version 4.0.17.
● Supports G.994.1 ITU G.hs.
● It supports reach-extended ADSL2 (G.922.3) Annex L for increased performance on loop
lengths greater than 16,000 feet from central office.
● The Cisco 880 Series complies with T1.413 ANSI ADSL DMT issue 2.
● Conforms to DSL Forum TR-067.
● The chipset does not provide interoperability with carrierless amplitude modulation/phase
modulation (CAP)-based ADSL lines.
● ADSL (G.992.1) provides downstream data rates of up to 8 Mbps and upstream data rates of
up to 0.8 Mbps.
● ADSL2 provides higher downstream rates of up to 12 Mbps and upstream data rates of up to 1
Mbps.
● The ADSL2+ standard (G.992.5) increases the downstream data rates of up to 24 Mbps and
upstream data rates of up to 1.5 Mbps.
● Annex M adds capabilities for extended upstream bandwidth above 2.0 Mbps.
● The series supports dying gasp.
● Broadcom Chipset
● Support for G.992.3 over basic telephone service only
● VDSL2 band plan supported: 997 and 998, over basic telephone service only
● VDSL2 profiles supported: 8a, 8b, 8c, 8d, 12a, 12b, and 17a
● Ethernet Packet Transport Mode (PTM) mode only
● IEEE 802.1q VLAN tagging
● Conexant / Ikanos ChipsetSupports 2- and 4-wire modes
● Offers symmetrical WAN speeds up to 2.304 Mbps over a single copper pair and up to 4.608
Mbps over two copper pairs using ITU-T G.991.2 Annex A and Annex B support for wetting
current (Section A.5.3.3 of G.991.2)
● Supports dying gasp; uses power status bit (Section 7.1.2.5.3 of G.991.2) for signaling
